emissions control devices and systems may be 
done by any automotive repair establishment or 
individuals using parts that are “certified” to 
EPA standards.
According to state and fede ral regulations, failure to 
perform maintenance on the maintenance main 
items marked with # will  not void your emissions 
warranties. However, all ma intenance services should 
be performed in accordan ce with the intervals 
indicated by the driver  information interface.

uuCleaning uExterior Care
Maintenance
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 no t 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 lo se their luster or appear burn ished. To avoid water stains, 
wipe the wheels dry with a cloth while they are still wet.
The inside lenses of exterior lights (headlig hts, 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 ma y result in moisture developing on the light lens frame 
surfaces. This also is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops 
building up inside the lenses, have your vehicle inspected by a dealer.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually 
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact 
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or 
replaced.
1. Park the vehicle on a firm, level, non-slippery surface and apply the parking brake.
2. Press the 
(P button.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Changing a Flat Tire
Follow compact spare precautions:
Periodically check the tire pressure of the compact 
spare. It should be set to the specified pressure. 
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the 
vehicle speed under 50 mph (80 km/h). Replace with 
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are 
specifically for this model. Do not use them with 
another vehicle. Do not us e another type of compact 
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire. 
If a chain-mounted front tire goes flat, remove one of 
the full-size rear tires and replace it with the compact 
spare tire. Remove the flat front tire and replace it 
with the full-size tire that  was removed from the rear. 
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire, 
as it can damage the tire pressure sensor.
Do not use the jack if it  doesn’t work properly. Call 
your dealer or a prof essional towing service.

uuIndicator, Comi ng On/BlinkinguIf the Brake System Indicator (Red) Comes On or Blinks
Handling the Unexpected
If the Brake System Indicator (Red) Comes On or 
Blinks
■Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■What to do when the indicator comes on while driving
Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid  level the next time you stop.
• If abnormal, take immediate acti on. If necessary, downshift the 
transmission to slow the vehicle using engine braking.
■Reasons for the indicator to blink
• There is a problem with the  electric parking brake system.
■What to do when the indicator blinks
• Avoid using the parking brake and have your vehicle checked by a 
dealer immediately.
1If the Brake System Indicator (Red) Comes On or Blinks
Have your vehicle re paired immediately.
It is dangerous to drive with  low brake fluid. If there 
is no resistance from  the brake pedal, stop 
immediately in a safe plac e. If necessary downshift 
the gears.
If the brake system indicator (red) and  ABS indicator 
come on simultaneously , the electronic brake 
distribution system is not wo rking. This can result in 
vehicle instability under sudden braking.
Have your vehicle inspecte d by a dealer immediately.
If the brake system indicator (red) blinks at the same 
time when the brake system indicator (amber) comes 
on, the parking br ake may not work.
Avoid using the parking brak e and have your vehicle 
checked by a dealer immediately.
