Operation Driving instructions

Control and operation of radio transmitters

Telephones and two-way radios

Modular COMAND System, radio and telephone*

Warning!

Do not forget that your primary responsibili- ty is to drive the vehicle. Only operate the Modular COMAND System, radio or tele- phone1 if road, weather and traffic condi- tions permit.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximate- ly 14 m) every second.

1 Observe all legal requirements.

Warning!

Never operate radio transmitters equipped with a built-in or attached antenna (i.e. with- out being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunc- tion of the vehicle’s electronic system, possibly resulting in an accident and/or personal injury.

Radio transmitters, such as a portable telephone or a citizens band unit should only be used inside the vehicle if they are connected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation instructions regarding use of an external antenna.

Operation Driving instructions

Catalytic converter

Your Mercedes-Benz is equipped with monolithic-type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial con- trol of the pollutants in the exhaust emis- sions. Keep your vehicle in proper operating condition by following our rec- ommended maintenance instructions as outlined in your Maintenance Booklet.

Warning!

As with any vehicle, do not idle, park or op- erate this vehicle in areas where combusti- ble materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

Emission control

To prevent damage to the catalytic con- verters, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and potentially start a fire.

Certain engine systems serve to keep the toxic components of the exhaust gases within permissible legal limits. These systems, of course, will function properly only when maintained strictly ac- cording to factory specifications. Any ad- justments on the engine should, therefore, be carried out only by qualified Mercedes-Benz Light Truck Center autho- rized technicians.

Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly accord- ing to Mercedes-Benz servicing require- ments. For details refer to the Maintenance Booklet.

Warning!

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause uncon- sciousness and possible death.

Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one win- dow fully open at all times.

340

Coolant temperature

During severe operating conditions and stop-and-go city traffic, the coolant tem- perature may rise to approx. 248°F (120°C). The engine should not be operated with the coolant temperature in the red zone. Doing so may cause serious engine dam- age which is not covered by the Mercedes-Benz Limited Warranty.

Warning!

앫 Driving when your engine is badly over-

heated can cause some fluids which may have leaked into the engine com- partment to catch fire. You could be se- riously burned.

앫 Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

Coolant level

The engine coolant is a mixture of water and anticorrosion/antifreeze. To check the coolant level, the vehicle must be parked on level ground and the engine must be cool.

Warning!

In order to avoid any possibly serious burns: 앫 Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indi- cates that the coolant is overheated.

앫 Do not remove pressure cap on coolant

reservoir if coolant temperature is above 158°F (70°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.

앫 Using a rag, slowly open the cap approx- imately 1/2 turn to relieve excess pres- sure. If opened immediately, scalding hot fluid and steam will be blown out un- der pressure.

앫 Do not spill antifreeze on hot engine

parts. Antifreeze contains ethylene gly- col which may burn if it comes into con- tact with hot engine parts.

During all seasons, add MB Windshield Washer Concentrate “S” to water. Premix the windshield washer fluid in a suitable container.

Warning!

Washer solvent/antifreeze is highly flamma- ble. Do not spill washer solvent/antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

왘 Use the tab to pull cap 1 upwards. 왘 Refill the reservoir with MB Windshield Washer Concentrate “S” and water (or commercially available premixed wind- shield washer solvent/antifreeze, de- pending on ambient temperatures). Always use washer solvent/antifreeze where temperatures may fall below freezing point. Failure to do so could result in damage to the washer system/reservoir.

왔 Tires and wheels See an authorized Mercedes-Benz Light Truck Center for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase.

Warning!

Replace rims or tires with the same designa- tion, manufacturer and type as shown on the original part. See an authorized Mercedes-Benz Light Truck Center for fur- ther information. If incorrectly sized rims and tires are mounted: 앫 The wheel brakes or suspension

components can be damaged.

앫 The operating clearance of the wheels and the tires may no longer be correct.

Warning!

Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them.

When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident.

Retreaded tires are not tested or recom- mended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used.

Operation Tires and wheels

Important guidelines

앫 Only use sets of tires and rims of the

same type and make.

앫 Tires must be of the correct size for the

rim.

앫 Break in new tires for approximately

60 miles (100 km) at moderate speeds.

앫 Regularly check the tires and rims for

damage. Dented or bent rims can cause tire inflation pressure loss and damage to the tire beads.

앫 If vehicle is heavily loaded, check tire

inflation pressure and correct as required.

앫 Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths under 1/8 in (3 mm).

앫 When replacing individual tires, you should mount new tires on the front wheels first (on vehicles with same-sized wheels all around).

353

Tire inspection Every time you check your tire inflation pressure, you should also inspect your tires for the following: 앫 excessive treadwear (컄 page 355) 앫 cord or fabric showing through the

tire’s rubber

Life of tire The service life of a tire is dependent upon varying factors including but not limited to: 앫 Driving style 앫 Tire inflation pressure 앫 Distance driven

앫 bumps, bulges, cuts, cracks or splits in

the tread or side of the tire

Warning!

Tires and spare tire should be replaced after 6 years, regardless of the remaining tread.

Replace the tire if you find any of the above conditions. Make sure you also inspect the spare tire periodically for condition and inflation. Spare tires will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.

Operation Tires and wheels

Tire care and maintenance

Warning!

Regularly check the tires for damage. Dam- aged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle.

Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them.

Regularly check your tire inflation pressure at least once a month. For more informa- tion on checking tire inflation pressure, see “Recommended tire inflation pres- sure” (컄 page 363).

354

Tread depth Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths under 1/8 in (3 mm). Treadwear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approx- imately 1/16 in (1.6 mm), at which point the tire is considered worn and should be replaced. Recommended minimum tire tread depth: 앫 Summer tires 1/8 in (3 mm) 앫 Winter tires 1/6 in (4 mm)

Warning!

Although the applicable federal motor safety laws consider a tire to be worn when the treadwear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recom- mend that you do not allow your tires

to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply re- duced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

1 TWI (Tread Wear Indicator) The treadwear indicator appears as a solid band across the tread.

Operation Tires and wheels

Storing tires

Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline.

Cleaning tires

Never use a round nozzle to power wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire.

Direction of rotation

Loading the vehicle

앫 The Certification label, also found on

Unidirectional tires offer added advan- tages, such as better hydroplaning perfor- mance. To benefit, however, you must make sure the tires rotate in the direction specified. An arrow on the sidewall indicates the intended direction of rotation (spinning) of the tire.

Spare wheels may be mounted against the direction of rotation (spinning) even with a unidirectional tire for temporary use only until the regular drive wheel has been repaired or replaced. Always observe and follow applicable tempo- rary use restrictions and speed limita- tions indicated on the spare wheel.

Two labels on your vehicle show how much weight it may properly carry. 앫 The Tire and Loading Information

placard (Example A) or the Vehicle Tire Information placard (Example B) can be found on the driver’s door B-pillar. This placard tells you important information about the number of people that can be in the vehicle and the total weight that can be carried in the vehicle. It also contains information on the proper size and recommended tire inflation pressures for the original equipment tires on your vehicle.

the driver’s door B-pillar tells you about the gross weight capacity of your vehi- cle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. The Certification label also tells you about the front and rear axle weight capacity, called the Gross Axle Weight Rating (GAWR). The GAWR is the total allowable weight that can be carried by a single axle (front or rear). Never exceed the GVWR or GAWR for either the front axle or rear axle.

356

Tire and Loading Information

Warning!

Do not overload the tires by exceeding the specified load limit as indicated on the plac- ard on the driver’s door B-pillar. Overloading the tires can overheat them, possibly caus- ing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

Your vehicle is equipped with either the Tire and Loading Information placard (Example A) or the Vehicle Tire Information placard (Example B).

The placard showing the load limit informa- tion is located on the driver’s door B-pillar. If your vehicle is equipped with the Vehicle Tire Information placard (Example B), locate the heading “Vehicle Capacity Weight” on this placard. The combined weight of all occupants, cargo/luggage and trailer tongue (if applicable) should never exceed the weight listed next to vehicle capacity weight.

Seating capacity The seating capacity gives you important information on the number of occupants that can be in the vehicle. Observe front and rear seating capacity. Depending on production date, your vehicle may be equipped with placard Example A or plac- ard Example B. Your vehicle may not be equipped with placard A nor other placard posting the seating capacity. If this is the case, legal requirements at time of production of your vehicle did not require manufacturers to post the seating capacity.

Never let more people ride in the vehicle than there are designated seating posi- tions and seat belts available. Be sure everyone riding in the vehicle is correctly restrained with a separate seat belt.

Data shown on placard examples are for illustration purposes only. Seating data are specific to each vehicle and may vary from data shown in the illus- tration below. Refer to placard on vehi- cle for actual data specific to your vehicle.

Operation Tires and wheels

Steps for determining correct load limit The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor Vehicle Safety Act of 1966”. Step 1 (Vehicles equipped with placard Example A) 왘 Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.

Step 1 (Vehicles equipped with placard Example B) 왘 Locate the heading “Vehicle Capacity

Weight” on your vehicle’s placard.

Step 2
왘 Determine the combined weight of the

driver and passengers that will be riding in your vehicle.

Step 3
왘 Subtract the combined weight of the driver and passengers from XXX kilograms or XXX lbs.

Step 4
왘 The resulting figure equals the avail-

able amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there will be five 150 lbs. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 x 150) = 650 lbs.)

Step 5
왘 Determine the combined weight of

luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4.

Step 6 (if applicable) 왘 If your vehicle will be towing a trailer,

load from your trailer will be trans- ferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (컄 page 362).

The following table shows examples on how to calculate total and cargo load capacities with varying seating configura- tions and number and size of occupants. The following examples use a load limit of 1500 lbs. This is for illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on the vehicle’s placard (컄 page 357).

361

Operation Tires and wheels

Certification label Even after careful determination of the combined weight of all occupants, cargo and the trailer tongue load (if applicable) (컄 page 362) as to not exceed the permis- sible load limit, you must make sure that your vehicle never exceeds the Gross Vehi- cle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for either the front or rear axle. You can obtain the GVWR and GAWR from the Certification la- bel. The Certification Label can be found on the driver’s door B-pillar, see “Technical data” (컄 page 510).

Gross Vehicle Weight Rating (GVWR): The total weight of the vehicle, all occupants, all cargo, and the trailer tongue load (컄 page 362) must never exceed the GVWR. Gross Axle Weight Rating (GAWR): The to- tal allowable weight that can be carried by a single axle (front or rear). To assure that your vehicle does not ex- ceed the maximum permissible weight limits (GVWR and GAWR for front and rear axle), have the loaded vehicle (including driver, passengers and all cargo and, if ap- plicable, trailer fully loaded) weighed on a suitable commercial scale.

Trailer tongue load The tongue load of any trailer is an impor- tant weight to measure because it affects the load you can carry in your vehicle. If a trailer is towed, the tongue load must be added to the weight of all occupants riding and any cargo you are carrying in the vehicle. The tongue load typically is between 10% and 15% of the trailer weight and everything loaded in it.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being over- heated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

Your vehicle is equipped with either the Tire and Loading Information placard (Ex- ample A) or the Vehicle Tire Information Placard (Example B) located on the driver's door B-pillar (컄 page 357). The tire inflation pressure should be checked regularly and should only be ad- justed on cold tires. The tires can be con- sidered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). Follow recommended cold tire inflation pressures listed on placard. Keeping the tires properly inflated provides the best handling, tread life and riding comfort. In addition to the tire placard on the driver’s door B-pillar, also consult the fuel filler flap for any additional information pertaining to special driving situations. For more information, see “Important notes on tire inflation pressure” (컄 page 364).

Be sure to readjust the tire inflation pressure for normal driving speeds. You should wait until the tires are cold before adjusting the tire inflation pressure. Some vehicles may have supplemental tire inflation pressure information for vehicle loads less than the maximum loaded vehi- cle condition. If such information is provid- ed, it can be found on the placard located on the inside of the fuel filler flap. Tire inflation pressure changes by approxi- mately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire inflation pressure where the temperature is different from the outside temperature.

Important notes on tire inflation pressure

Warning!

If the tire inflation pressure drops repeated- ly: 앫 Check the tires for punctures from

foreign objects.

앫 Check to see whether air is leaking from

the valves or from around the rim.

Tire temperature and tire inflation pressure are also increased while driving, depending on the driving speed and the tire load. If you will be driving your vehicle at high speeds of 100 mph (160 km/h) or higher, where it is legal and conditions allow, consult the placard on the inside of the fuel filler flap on how to adjust the cold tire in- flation pressure. If you do not adjust the tire inflation pressure, excessive heat can build up and result in sudden tire failure.

Checking tire inflation pressure

Regularly check your tire inflation pressure at least once a month. Check and adjust the tire inflation pressure when the tires are cold. The tires can be considered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). If you check the tire inflation pressure when the tires are warm (the vehicle has been driven for several miles or sitting less than 3 hours), the reading will be approximately 4 psi (0.3 bar) higher than the cold reading. This is normal. Do not let air out to match the specified cold tire inflation pressure. Otherwise, the tire will be underinflated.

Warning!

Follow recommended tire inflation pressures.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being over- heated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

Do not overload the tires by exceeding the specified load limit as indicated on the plac- ard on the driver’s door B-pillar. Overloading the tires can overheat them, possibly caus- ing a blowout.

Operation Tires and wheels

Checking tire inflation pressure manually Follow the steps below to achieve correct tire inflation pressure: 왘 Remove the cap from the valve on one

tire.

왘 Firmly press a tire gauge onto the

valve.

왘 Read tire inflation pressure on tire gauge and check against the recom- mended tire inflation pressure on the placard on the driver’s door B-pillar (컄 page 357) or, if available, the inside of the fuel filler flap. If necessary, add air to achieve the recommended tire in- flation pressure.

컄컄

365

Operation Tires and wheels

컄컄

If you have overfilled the tire, release tire inflation pressure by pushing the metal stem of the valve with e.g. a tip of a pen. Then recheck the tire inflation pressure with the tire gauge.

왘 Install the valve cap. 왘 Repeat this procedure for each tire.

366

Run Flat Indicator (Canada only) While the vehicle is being driven, the Run Flat Indicator monitors the set tire inflation pressures by evaluating each wheel’s rota- tional speed. This allows the system to de- tect a significant loss of pressure in a tire. If a wheel’s rotational speed changes due to falling tire inflation pressure, you will see a corresponding warning message in the multifunction display. The Run Flat Indicator may function in a re- stricted manner or with a delay if: 앫 snow chains are mounted to the

vehicle

앫 winter road conditions prevail 앫 you are driving on a loose surface (e.g.

sand or gravel)

앫 you are driving in a very sporty manner

(involving rapid acceleration or high speeds in curves)

Warning!

When the multifunction display shows the message Tire pressure Check tires, one or more of your tires is significantly un- der-inflated. You should stop and check your tires as soon as possible, and inflate them to the proper tire inflation pressure as indicated on the vehicle’s tire information placard. Driving on a significantly under-in- flated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended tire infla- tion pressure as specified in the vehicle placard and owner’s manual.

i The recommended tire inflation pres- sures for your vehicle can be found on the tire placard located on the driver’s door B-pillar (컄 page 357). The tire in- flation pressures are not listed in the owner’s manual.

Warning!

The Run Flat Indicator does not indicate a warning for wrongly selected tire inflation pressures. Always adjust tire inflation pres- sure according to the placard on the driver’s door B-pillar or fuel filler flap.

The Run Flat Indicator does not replace reg- ular checks of the tire inflation pressures since a gradual pressure loss in all four tires cannot be detected by the Run Flat Indicator.

The Run Flat Indicator is not able to issue a warning due to a sudden dramatic loss of tire inflation pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully apply- ing the brakes and avoiding abrupt steering maneuvers.

Operation Tires and wheels

Reactivating the Run Flat Indicator The tire inflation pressure monitor must be reactivated in the following situations: 앫 If you have changed the tire inflation

pressure

앫 If you have replaced the wheels or tires 앫 If you have installed new wheels or

tires

왘 Using the tire placard on the driver’s door B-pillar or, if available, the inside of the fuel filler flap, make sure the tire inflation pressure of all four tires is cor- rect.

Warning!

The Run Flat Indicator can only warn you in a reliable manner if you have set the correct tire inflation pressures for each tire.

If an incorrect tire inflation pressure was set, the system will monitor the pressure ac- cording to the incorrect value.

Checking tire pressure electronically with the Tire Pressure Monitoring System (TPMS), (USA only)

The Tire Pressure Monitoring System (TPMS) is equipped with a combination low tire pressure/TPMS malfunction telltale in the instrument cluster (컄 page 24). Depending on how the telltale illuminates, it indicates a low tire pressure condition or a malfunction in the TPMS system itself: 앫 If the telltale illuminates continu- ously, one or more of your tires is significantly underinflated. There is no malfunction in the TPMS.

앫 If the telltale flashes for 60 seconds

and then stays illuminated, the TPMS system itself is not operating properly.

Operation Tires and wheels

The TPMS only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire inflation pres- sure, as selected by the driver, in all four tires. A warning is issued to alert you to a decrease in pressure in one or more of the tires.

Warning!

The TPMS does not indicate a warning for wrongly selected inflation pressures. Always adjust tire inflation pressure according to the placard on the driver’s door B-pillar or, if available, the supplemental tire pressure in- formation on the inside of the fuel filler flap.

The TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by care- fully applying the brakes and avoiding abrupt steering maneuvers.

Warning!

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the vehicle placard or the tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or the tire inflation pressure label, you should determine the proper tire infla- tion pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitor- ing system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accord- ingly, when the low tire pressure telltale illu- minates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significant- ly underinflated tire causes the tire to over- heat and can lead to tire failure.

Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is com- bined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then remain continuously illuminated. This sequence will continue upon subse- quent vehicle start-ups as long as the mal- function exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

컄컄

369

Operation Tires and wheels

컄컄

TPMS malfunctions may occur for a variety of reasons, including the installation of in- compatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

370

If a condition causing the TPMS to mal- function develops, it may take up to 10 minutes for the system to signal a malfunction using the TPMS telltale flashing and illumination sequence. The telltale extinguishes after a few minutes driving if the malfunction has been corrected.

Operating radio transmission equip- ment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the TPMS to malfunction.

Reactivating the TPMS The TPMS must be reactivated when you have adjusted the tire inflation pressure to a new level (e.g. because of different load or driving conditions). The TPMS is then recalibrated to the current tire inflation pressures.

Warning!

It is the driver’s responsibility to calibrate the TPMS on the recommended cold infla- tion pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

왘 Using the tire placard on the driver’s door B-pillar (컄 page 357) or, if avail- able, the supplemental tire pressure information on the inside of the fuel filler flap (컄 page 342), make sure the tire inflation pressure of all four tires is correct.

Operation Tires and wheels

Reactivate the TPMS after adjusting the tire inflation pressure to the infla- tion pressure recommended for the vehicle operating condition. Tire pres- sure should only be adjusted on cold tires. Observe the recommended tire inflation pressure on the placard on the driver’s door B-pillar (컄 page 357). Some vehicles may have supplemental tire pressure information for driving at high speeds (컄 page 364) or for vehicle loads less than the maximum loaded vehicle condition (컄 page 364). If such information is provided, it can be found on the inside of the fuel filler flap.

Checking tire pressure electronically with the Advanced Tire Pressure Moni- toring System* (Advanced TPMS*), (Canada only)

The Advanced Tire Pressure Monitoring System* (Advanced TPMS*) is equipped with a combination low tire pressure/TPMS malfunction telltale in the instrument cluster (컄 page 24). De- pending on how the telltale illuminates, it indicates a low tire pressure condi- tion or a malfunction in the TPMS sys- tem itself: 앫 If the telltale illuminates continu- ously, one or more of your tires is significantly underinflated. There is no malfunction in the TPMS.

앫 If the telltale flashes for 60 seconds

The TPMS only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire inflation pres- sure, as selected by the driver, in all four tires. A warning is issued to alert you to a decrease in pressure in one or more of the tires. Tire pressure inquiries are made using the multifunction display. The present inflation pressures are displayed only after a few minutes’ travel time.

Possible differences between the read- ings of a tire pressure gauge of an air hose, e.g. gas station equipment, and the vehicle’s control system can occur. Usually the readings issued by the con- trol system are more precise.

왘 Switch on the ignition (컄 page 38). 왘 Press the j or k button until

the current inflation pressures for each tire appear in the multifunction display.

372

When the message Tire pressure displayed only after driving a few minutes appears in the multifunction display, the individual inflation pres- sure values are matched with the tires. The individual values are displayed af- ter a few minutes driving.

Warning!

It is the driver’s responsibility to calibrate the TPMS on the recommended cold infla- tion pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

With a spare wheel without wheel sen- sor mounted, the system may still indi- cate the tire inflation pressure of the removed wheel for some minutes. If this happens, keep in mind that the in- dicated value where the spare wheel is mounted does not reflect the actual spare tire inflation pressure.

Warning!

The TPMS does not indicate a warning for wrongly selected inflation pressures. Always adjust tire inflation pressure according to the placard on the driver’s door B-pillar or, if available, the supplemental tire pressure in- formation on the inside of the fuel filler flap.

The TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by care- fully applying the brakes and avoiding abrupt steering maneuvers.

For illustration purposes only. Actual data on tires are specific to each vehi- cle and may vary from data shown in above illustration.

General: Depending on the design standards used, the tire size molded into the sidewall may have no letter or a letter preceding the tire size designation. No letter preceding the size designation (as illustrated above): Passenger car tire based on European design standards. Letter “P” preceding the size designation: Passenger car tire based on U.S. design standards. Letter “LT” preceding the size designation: Light Truck tire based on U.S. design standards. Letter “T” preceding the size designation: Temporary spare tires which are high pressure compact spares designed for temporary emergency use only.

Tire width The tire width 1 (컄 page 376) indicates the nominal tire width in mm.

Aspect ratio The aspect ratio 2 (컄 page 376) is the dimensional relationship between tire section height and section width and is expressed in percentage. The aspect ratio is arrived at by dividing section height by section width.

Tire code The tire code 3 (컄 page 376) indicates the tire construction type. The “R” stands for radial tire type. Letter “D” means diag- onal or bias ply construction; letter “B” means belted-bias ply construction. At the tire manufacturer’s option, any tire with a speed capability above 149 mph (240 km/h) can include a “ZR” in the size designation (for example: 245/40 ZR 18). For additional information, see “Tire speed rating” (컄 page 378).

Rim diameter The rim diameter 4 (컄 page 376) is the diameter of the bead seat, not the diameter of the rim edge. Rim diameter is indicated in inches (in).

Tire load rating The tire load rating 5 (컄 page 376) is a numerical code associated with the maximum load a tire can support. For example, a load rating of 91 corre- sponds to a maximum load of 1356 lbs (615 kg) the tire is designed to support. See also “Maximum tire load” (컄 page 382) where the maximum load as- sociated with the load index is indicated in kilograms and lbs.
