Winter Tires

If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires, 
or tire chains; reduce speed; and maintain sufficient distance between vehicles when 
driving.

Be particularly careful when operating the steering wheel or brakes to prevent 
skidding.

Use tire chains, snow tires, or all season tires when necessary or according to the law.

When mounting, refer to the following points.

For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the 

chains listed below:

• Follow the chain manufacturer's instruction when installing. Mount them as 

tightly as you can.

• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.

Cable-type: SCC Radial Chain SC1032

Winter Tires

NOTICE

Traction devices that are the wrong size or improperly 
installed can damage your vehicle's brake lines, 
suspension, body, and wheels. Stop driving if they are 
hitting any part of the vehicle.

When tire chains are mounted, follow the chain 
manufacturer's instructions regarding vehicle 
operational limits.

If your vehicle is equipped with summer tires, be 
aware that these tires are not designed for winter 
driving conditions. For more information, contact a 
dealer.

WARNING

Using the wrong chains, or not properly 
installing chains, can damage the brake 
lines and cause a crash in which you can be 
seriously injured or killed.

Follow all instructions in this owner's 
manual regarding the selection and use of 
tire chains.

Interior Care

Do not spill liquids inside the vehicle. Electrical 
devices and systems may malfunction if liquids are 
splashed on them.

Do not use silicone based sprays on electrical devices 
such as audio devices and switches. Doing so may 
cause the items to malfunction or cause a fire inside 
the vehicle.
If a silicone based spray is inadvertently used on 
electrical devices, consult a dealer.

Depending on their composition, chemicals and 
liquid aromatics may cause discoloration, wrinkles, 
and cracking to resin-based parts and textiles.
Do not use alkali solvents or organic solvents such as 
benzene or gasoline.

After using chemicals, make sure to gently wipe them 
away using a dry cloth.

Maintaining Genuine Leather

It is important to clean or wipe away dirt or dust as 
soon as possible. Spills can soak into leather resulting 
in stains. Dirt or dust can cause abrasions in the 
leather. In addition, please note that some dark 
colored clothing can rub onto the leather seats 
resulting in discoloration or stains.

Exterior Care

Dust off the vehicle body after you drive.
Regularly inspect your vehicle for scratches on painted surfaces. A scratch on a 
painted surface can result in body rust. If you find a scratch, promptly repair it.

Wash the vehicle regularly. Wash more frequently when driving in the following 
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.

• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic intermittent wipers, turn the wipers off.

• Keep sufficient distance between the cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to 

enter the vehicle interior.

• Do not spray high pressure water directly into the engine compartment. Instead, 

use low pressure water and a mild detergent.

A good coat of automotive body wax helps protect your vehicle’s paint from the 
elements. Wax will wear off over time and expose your vehicle’s paint to the 
elements, so reapply as necessary.

If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they 
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and 
clean water.

Wipe using a glass cleaner.

Aluminum is susceptible to deterioration caused by salt and other road 
contaminants. When necessary, as early as possible use a sponge and mild detergent 
to wipe away these contaminants. Do not use a stiff brush or harsh chemicals 
(including some commercial wheel cleaners). These can damage the protective finish 
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish, 
the wheels also may lose their luster or appear burnished. To avoid water stains, 
wipe the wheels dry with a cloth while they are still wet.

The inside lenses of exterior lights (headlights, brake lights, etc.) may fog temporarily 
if you have driven in the rain, or after the vehicle has been run through a car wash. 
Dew condensation also may build up inside the lenses when there is a significant 
enough difference between the ambient and inside lens temperatures (similar to 
vehicle windows fogging up in rainy conditions). These conditions are natural 
processes, not structural design problems in the exterior lights.
Lens design characteristics may result in moisture developing on the light lens frame 
surfaces. This also is not a malfunction.
However, if you see large amounts of water accumulation, or large water drops 
building up inside the lenses, have your vehicle inspected by a dealer.

Accessories and Modifications

Accessories

When installing accessories, check the following:
• Do not install accessories on the windshield. They can obstruct your view and 

delay your reaction to driving conditions.

• Do not install any accessories over areas marked SRS Airbag, on the sides or backs 

of the front seats, on front or side pillars, or near the side windows. 
Accessories installed in these areas may interfere with proper operation of the 
vehicle’s airbags or may be propelled into you or another occupant if the airbags 
deploy.

• Be sure electronic accessories do not overload electrical circuits or interfere with 

proper operation of your vehicle.

2 Fuses P. 519

• Before installing any electronic accessory, have the installer contact a dealer for 

assistance. If possible, have a dealer inspect the final installation.

Modifications

Do not modify your vehicle in a manner that may affect its handling, stability, or 
reliability, or install non-genuine Acura parts or accessories that may have a similar 
effect.

Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is properly installed and maintained, and do not 
make any modification to your vehicle or its systems that might cause your vehicle 
to no longer meet federal, state, province, territory, and local regulations.

The on-board diagnostic port (OBD-II/SAE J1962 connector) installed on this vehicle 
is intended to be used with automobile system diagnostic devices or with other
