Off-Highway Driving Guidelines
Crossing a Stream Avoid driving through deep water. If you encounter water in your route (a small stream or large puddle, for example), evaluate it carefully before going ahead. Make sure it is shallow, flowing slowly, and has firm ground underneath. If you are not sure of the depth or the ground, turn around and find another route.
Driving through deep water can also damage your vehicle. The water can get into the transmission and differential, diluting the lubricant and causing an eventual failure. It can also wash the grease out of the wheel bearings.
If You Get Stuck Avoid driving on soft sand, deep mud, or other surfaces where you could get stuck. If you do happen to get stuck because of inclement weather or other conditions, choose a safe and appropriate course of action.
If you spin the wheels excessively trying to get unstuck, you may overheat the components of the SH-AWD system. The SH-AWD indicator on the instrument panel will blink to indicate the rear differential temperature is too high.
You should never use a jack to try getting unstuck. A jack only works on firm, level ground. Also, your vehicle could easily slip off the jack and hurt you or someone else.
You will also see an ‘‘SH-AWD DIFF TEMP HIGH’’ message on the multi- information display (see page ).
78
If this happens, stop and allow everything to cool down. The SH-AWD indicator goes off after the rear differential temperature drops.

Important Maintenance Precautions If you have the required service done but do not reset the display, or reset the display without doing the service, the system will not show the proper maintenance intervals. This can lead to serious mechanical problems because you will no longer have an accurate record of when maintenance is needed.
Your authorized Acura dealer knows your vehicle best and can provide competent, efficient service. However, service at a dealer is not mandatory to keep your warranties in effect. Maintenance may be done by any qualified service facility or person who is skilled in this type of automotive service. Keep all receipts as proof of completion, and have the person who does the work fill out your Maintenance Journal or Canadian Maintenance Log. Check your warranty booklet for more information.
We recommend using Acura parts and fluids whenever you have maintenance done. These are manufactured to the same high- quality standards as the original components, so you can be confident of their performance and durability.

Inspect drive belt Replace transmission and transfer fluid
Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission and transfer fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs Inspect valve clearance Replace engine coolant Replace rear differential fluid
Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (shear) stress to fluid. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Required Engine Oil
Oil is a major contributor to your
engine’s performance and longevity.
Your vehicle is equipped with a high-
performance turbocharged engine
that requires the use of synthetic
motor oil. Always use Mobil 1
5W-30 or an equivalent oil that meets
the Acura HTO-06 standard. Not all
synthetic oils will meet this standard.
Only use oils that display the
HTO-06 standard on the label.
Failure to use Mobil 1 or an
equivalent oil that meets the HTO-06
standard can lead to a reduction in
engine performance or durability,
and can cause engine damage not
covered by your warranty.

Replacing a Front Fog Light Bulb Your vehicle uses halogen light bulbs. When replacing a bulb, handle it by its plastic case, and protect the glass from contact with your skin or hard objects. If you touch the glass, clean it with denatured alcohol and a clean cloth.
Halogen bulbs get very hot when lit. Oil, perspiration, or a scratch on the glass can cause the bulb to overheat and shatter.

Floor Mats
LOOP
If you use a non-Acura floor mat, make sure it fits properly and that it can be used with the floor mat anchors. Do not put additional floor mats on top of the anchored mats.
If your seat belts get dirty, use a soft brush with a mixture of mild soap and warm water to clean them. Do not use bleach, dye, or cleaning solvents. Let the belts air-dry before you use the vehicle. Dirt build-up in the loops of the seat belt anchors can cause the belts to retract slowly. Wipe the insides of the loops with a clean cloth dampened in mild soap and warm water or isopropyl alcohol.
354
FLOOR MAT ANCHORS
The driver’s and front passenger’s floor mats that came with your vehicle hook over the floor mat anchors. To lock each anchor, turn the knob clockwise. This keeps the floor mats from sliding forward (possibly interfering with the pedals), or backwards (making the front passenger’s weight sensors ineffective). If you remove a floor mat, make sure to re-anchor it when you put it back in your vehicle.

INTERCOOLER
Your vehicle is equipped with a intercooler on the engine to cool the air flow from a turbo charger into the engine. The intercooler fins bend easily. Do not push them with your finger.
Your vehicle is equipped with an antenna at the rear of the roof . Bef ore using a ‘‘drive-through’’ car wash, remove the antenna by unscrewing it by hand. This prevents the antenna f rom being damaged by the car wash brushes.
Do not spray water (f rom such sources as garden hoses, high pressure sprayers) into the engine compartment. It may cause serious damage to your vehicle, and could also damage the intercooler f ins.
Dust and Pollen Filter This filter removes the dust and pollen that is brought in from the outside through the climate control system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
information display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the flow from
the climate control system becomes
less than usual.

Wiper Blades
Check the condition of the wiper blades at least every six months. Replace them if you find signs of cracking in the rubber, areas that are getting hard, or if they leave streaks and unwiped areas when used.
WIPER ARMS
To replace a front wiper blade:
1.
Raise each wiper arm off the windshield, lifting the driver’s side first, then the passenger’s side.
Do not open the hood when the wiper arms are raised, or you will damage the hood and the wiper arms.
2.
Disconnect the blade assembly from the wiper arm:
Press and hold the lock tab. Slide the blade assembly toward the lock tab until it releases from the wiper arm.
When replacing a wiper blade, make sure not to drop the wiper blade or wiper arm down on the windshield.

Wiper Blades, Wheels
Wheels Clean the wheels as you would the rest of the exterior. Wash them with the same solution, and rinse them thoroughly.
Aluminum alloy wheels have a protective clear-coat that keeps the aluminum from corroding and tarnishing. Cleaning the wheels with harsh chemicals (including some commercial wheel cleaners) or a stiff brush can damage the clear-coat. To clean the wheels, use a mild detergent and a soft brush or sponge.

Tires
To safely operate your vehicle, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated.
The following pages give more detailed information on how to take care of your tires and what to do when they need to be replaced.
Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed.
Follow all instructions in this owner’s manual regarding tire inflation and maintenance.
360
Inflation Guidelines Keeping the tires properly inflated provides the best combination of handling, tread life, and riding comfort.
Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.
Overinflated tires can make your vehicle ride more harshly, are more prone to damage from road hazards, and wear unevenly.
The tire pressure monitoring system (TPMS) will warn you when a tire pressure is low. See page for information on the TPMS.
307
Even though your vehicle is equipped with TPMS, we recommend that you visually check your tires every day. If you think a tire might be low, check it immediately with a tire gauge.
Use a gauge to measure the air pressure in each tire at least once a month. Even tires that are in good condition may lose 1 to 2 psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm ) per month. Remember to check the spare tire at the same time.
Check the air pressures when the
tires are cold. This means the
vehicle has been parked for at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures.

Tires
Recommended Tire Pressures The following charts show the recommended cold tire pressures for most normal driving conditions.
Tire Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear.
Tire Size
P235/55R18 99V
Cold Tire Pressure for Normal Driving Front/Rear: 32 psi (220 kPa , 2.2 kgf/cm )
The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm )
For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver’s doorjamb.
You should look for:
Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these conditions.
Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or cord.
Excessive tread wear.
