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.

after cleaning, turn the knobs to the lock 
position.

Do not put additional floor mats on top of 
the anchored mat.

To properly clean leather:

1.

Use a vacuum or soft dry cloth first to remove any dirt or dust.

2.

Clean the leather with a soft cloth dampened with a solution comprised of 90% 
water and 10% neutral soap.

3.

Wipe away any soap residue with a clean damp cloth.

4.

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.

•

Turn off the automatic intermittent wipers.

Washing the Vehicle

Do not spray water into the air intake vents. It can 
cause a malfunction.

Do not spray water onto the capless unit when the 
fuel fill door is open. It can cause damage to the fuel 
system or engine.

•

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

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.

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 
devices that Acura has approved. Use of any other type of device may adversely 
affect the vehicle’s electronic systems or allow them to be compromised, possibly 
resulting in a system malfunction, drained battery, or other unexpected problems.

Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system 
or otherwise modify vehicle electrical systems. Disassembling or modifying electrical 
equipment can result in a crash or a fire.

If you ever need to replace your vehicle’s high-voltage battery assembly outside of 
warranty coverage, we highly recommend that you only use a genuine Acura high-
voltage battery assembly. Genuine Acura high-voltage battery assemblies are 
designed to work with your vehicle’s hybrid power system and have been designed, 
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have been similarly designed, engineered and 
manufactured, and installation of such assemblies could result in overcharging, fires, 
loss of power, or other conditions that may increase the likelihood of a crash or 
injury.

If a Tire Goes Flat

Temporarily Repairing a Flat Tire

If the tire has a large cut or is otherwise severely damaged, you will need to have the 
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can 
use the temporary tire repair kit so that you can drive to the nearest service station 
for a more permanent repair.

If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually 
to reduce speed. Then stop in a safe place.
