Care General notes Regular care of your vehicle is a condition for retaining the quality in the long term. Use care products and cleaning agents rec- ommended and approved by Mercedes-Benz. ! For cleaning your vehicle, do not use any
of the following: Rdry, rough or hard cloths Rabrasive cleaning agents Rsolvents Rcleaning agents containing solvents Do not scrub. Do not touch the surfaces or protective films with hard objects, e.g. a ring or ice scraper. You could otherwise scratch or damage the surfaces and protective film. H Environmental note Dispose of empty packaging and cleaning cloths in an environmentally responsible man- ner.
! Do not park up the vehicle for an extended period straight after cleaning it, particularly
292 Care
after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Care of the exterior Automatic car wash G WARNING Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, following a car wash, drive with particular care until the brakes are dry.
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This corresponds with the specifications for cabriolet programmes. In car washes that use high water pressures, there is a risk that a small amount of water may leak into the vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
! Make sure that the automatic car wash is suitable for the size of the vehicle. Fold in the exterior mirrors before the vehicle is washed. The exterior mirrors could other- wise be damaged.
! Make sure that the automatic transmis- sion is in position N when washing your vehicle in a tow-through car wash. The vehi- cle could be damaged if the transmission is in another position.
! Make sure that:
Rthe side windows and sliding sunroof are
closed completely.
Rthe blower for the ventilation/heating is switched off (airflow control is turned to
position 0/the à and Á buttons are switched off).
Rthe windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged. You can wash the vehicle in an automatic car wash from the very start. Wash off excess dirt before cleaning the vehi- cle in an automatic car wash. After using an automatic car wash, wipe off wax from the windscreen and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the wind- screen.
High-pressure cleaning equipment G WARNING Do not use high-pressure cleaners with circu- lar-jet nozzles (dirt grinders) to clean your vehicle, in particular the tyres. You could oth- erwise damage the tyres and cause an acci- dent.
! Always maintain a distance of at least 30 cm between the vehicle and the high- pressure cleaner nozzle. Information about the correct distance is available from the equipment manufacturer. Move the high-pressure cleaner nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtyres Rdoor gaps, roof gaps, joints etc. Rsoft top (Cabriolet) Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim elements Rventilation slots Damaged seals or electrical components can lead to leaks or failures.
Cleaning the G-Class Cabriolet soft top ! Never use any of the following to clean the
soft top: Rpetrol Rthinner Rtar or stain remover Rother organic solvents
! Remove bird droppings immediately as
they are corrosive and, therefore, can make the soft-top fabric leak. Do not use high- pressure cleaning equipment to clean the vehicle. Do not use sharp-edged equipment to remove ice and snow.
X Light soiling: you can clean the soft top while it is dry or rinse it with clear water. X Normal to heavy soiling: clean the soft top with a brush and clear water. Clean stains and other heavy soiling with a brush and suitable soft-top cleaning agents. Always brush in the direction of the fabric, from front to back.
Frequent cleaning reduces the soft top's resistance to dirt. To restore this resistance, clean your soft top with Mercedes-Benz Cabriolet care products. Incorrect cleaning and care, as well as ageing, can cause the soft-top seams to leak. Have the soft-top seams sealed at a qualified spe- cialist workshop. i Cover the soft top appropriately if you
plan to leave the vehicle outside for a long period of time.
Cleaning the wheels ! Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.
! Do not park up the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you
Care 293
should drive for a few minutes after clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Cleaning the paintwork ! Do not affix:
Rstickers Rfilms Rmagnetic plates or similar items to painted surfaces. You could otherwise damage the paintwork.
Scratches, corrosive deposits, areas affected by corrosion and damage caused by inade- quate care cannot always be completely repaired. In such cases, visit a qualified spe- cialist workshop. X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard. X Soak insect remains with insect remover and rinse off the treated areas afterwards. X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils, fuels and greases by rubbing gently with a cloth soaked in petroleum ether or lighter fluid.
X Use tar remover to remove tar stains. X Use silicone remover to remove wax.
Care and treatment of matt paintwork ! Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! Never use paint cleaner, buffing or pol- ishing products, or gloss preserver, e.g. wax. These products are only suitable for high-gloss surfaces. Their use on vehicles with matt finish leads to considerable sur- face damage (shiny, spotted areas). Always have paintwork repairs carried out at a qualified specialist workshop.
294 Care
! Do not use wash programs with a hot wax
treatment under any circumstances.
If your vehicle has a clear matt finish, observe the following instructions in order to avoid damage to the paintwork due to incorrect care. These notes also apply to light-alloy wheels with a clear matt finish. i The vehicle should preferably be washed by hand using a soft sponge, car shampoo and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and approved Mercedes-Benz care products.
Cleaning the windows G WARNING Switch off the windscreen wipers and remove the key from the ignition lock before cleaning the windscreen or the wiper blades. The wind- screen wipers could otherwise move and injure you.
! Do not use dry cloths, abrasive products, solvents or cleaning agents containing sol- vents to clean the inside of the windows. Do not touch the insides of the windows with hard objects, e.g. an ice scraper or ring. There is otherwise a risk of damaging the windows.
! Clean the water drainage channels of the windscreen and the rear window at regular intervals. Deposits such as leaves, petals and pollen may under certain circumstan- ces prevent water from draining away. This can lead to corrosion damage and damage to electronic components.
X Clean the inside and outside of the win- dows with a damp cloth and a cleaning agent that is recommended and approved by Mercedes-Benz.
Cleaning the wiper blades G WARNING Switch off the windscreen wipers and remove the key from the ignition lock before cleaning the windscreen or the wiper blades. The wind- screen wipers could otherwise move and injure you.

Battery (vehicle) Important safety notes Work on the battery, e.g. removing or instal- ling, requires specialist knowledge and the use of special tools. Therefore, always have work on the battery carried out at a qualified specialist workshop. G WARNING Work carried out incorrectly on the battery can, for example, lead to a short circuit and damage your vehicle's electronic system. This can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP® (Elec- tronic Stability Program). RIf ABS malfunctions, the wheels can lock during braking. This limits the steerability of the vehicle when braking and the braking distance may increase. There is a risk of accident.
RIf ESP® malfunctions, the vehicle will not be stabilised if it starts to skid or a wheel starts to spin. There is a risk of accident.
You should therefore have all work involving the battery carried out at a qualified specialist workshop.
306 Battery (vehicle)
G WARNING During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion. RMake sure that the positive terminal of a

There is a risk of an explosion. Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery. G WARNING During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion. RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery. RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected. RIt is particularly important to observe the described order when connecting and disconnecting
the jump leads.
RNever connect or disconnect the battery terminals while the engine is running. G WARNING A discharged battery can freeze at temperatures below freezing point. When jump-starting the vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion. Allow the frozen battery to thaw out before charging it or jump-starting. G WARNING Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid repeated and lengthy starting attempts.
! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may dam-
age the catalytic converter and create a risk of fire.

Jump-starting
Do not use a rapid charging device to start the vehicle. Make sure the jump leads are not damaged. Make sure the jump leads are not touching any other metal objects when they are connected to the battery.
If the indicator/warning lamps do not light up at temperatures around or below freezing point, the discharged battery is likely to be frozen (a commonplace scenario). In this case, do not jump-start the vehicle or recharge the battery. Once the battery has thawed out, its service life may be dramatically reduced. The starting characteristics can be impaired, particularly at low temperatures. It is recommended that you have the thawed out battery checked at a qualified specialist workshop. Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jump leads. Observe the following points: RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
RVehicles with a petrol engine: only jump-start the vehicle when the engine and exhaust
system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first. RJump-starting may only be performed from batteries with a nominal voltage of 12 V. ROnly use jump leads that have a sufficient cross-section and insulated terminal clamps. RIf the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
RMake sure that the two vehicles do not touch. Make sure that: RThe jump leads are not damaged. RNon-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
RThe jump leads cannot come into contact with parts such as the pulley or the fan. These
parts move when the engine is started and while it is running.

any qualified specialist workshop.
Towing and tow-starting Important safety notes G WARNING The vehicle is braked when the HOLD function or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the vehicle is to be towed.
! You may tow the vehicle for a maximum of 50km. A towing speed of 50 km/h must not be exceeded.
312 Towing and tow-starting
For towing distances over 50 km, the entire vehicle must be lifted up and transported. ! Only secure the tow cable or towing bar to the towing eyes. You could otherwise damage the vehicle.
! Do not use the towing eyes for recovery purposes as this could damage the vehicle. If in doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the vehicles could be damaged.
! Your vehicles is equipped with an auto- matic transmission. Therefore, you must not have the vehicle tow-started. The trans- mission may otherwise be damaged. G WARNING If the weight of the vehicle to be towed or tow- started is greater than the permissible gross weight of your vehicle: Rthe towing eye could detach itself Rthe vehicle/trailer combination could over-
turn.
There is a risk of an accident. When towing or tow-starting another vehicle, its weight should not be greater than the per- missible gross weight of your vehicle.
Information on your vehicle's gross vehicle weight rating can be found on the vehicle identification plate (Y page 336). Observe the legal requirements for the rele- vant countries when towing. It is better to have the vehicle transported than to have it towed. If the transfer case can be shifted into neutral N, you can tow the vehicle. If the transfer case cannot be shifted into neutral N, you can tow the vehicle with one axle raised. Please bear the following in mind: Rremove the propeller shaft between the
transfer case and the rolling axle.
Rturn the key to position 1 in the ignition lock
(Y page 143).
The battery must be connected and charged. Otherwise, you: Rcannot turn the key in the ignition lock to
position 2(Y page 143)
Rcannot shift the automatic transmission to
position N
i Deactivate the automatic locking feature (Y page 74). You could otherwise be locked out when pushing or towing the vehicle. Deactivate tow-away protection before the vehicle is towed (Y page 65).

Electrical fuses Important safety notes G WARNING Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct fuse rating for the systems con- cerned. Do not attempt to repair or bridge faulty fuses. Using fuses which have not been approved or attempting to repair or bridge faulty fuses could cause the fuse to be over- loaded and result in a fire. Have the cause
traced and rectified at a qualified specialist workshop.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which have the correct fuse rating for the system concerned. Otherwise, components or sys- tems could be damaged.
The fuses in your vehicle serve to disconnect faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions will fail. Blown fuses must be replaced with fuses of the same rating, which you can recognise by the colour and fuse rating. The fuse ratings are listed in the fuse allocation chart. If the newly inserted fuse also blows, have the cause traced and rectified at a qualified spe- cialist workshop, e.g. a Mercedes-Benz Service Centre.
Before replacing a fuse X Park the vehicle and apply the parking
brake.
X Switch off all electrical consumers. X Remove the key from the ignition lock.
All indicator lamps in the instrument cluster must be off.
The fuses are located in various fuse boxes: RMain fuse box on the driver's side of the
dashboard
RFuse box in the front-passenger footwell RFuse box in the transmission tunnel RFuse box in the battery case The fuse allocation chart and the spare fuses are in the main fuse box on the dashboard (Y page 315). You will find the fuse removal device in the vehicle tool kit (Y page 302).
