uuCleaning uExterior Care
Maintenance
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 may result in mo isture 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 firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to 
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF 
(LOCK).
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.

uuIndicator, Comin g On/BlinkinguIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■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.
If the Electric Power Steeri ng (EPS) System Indicator 
Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with the EPS system.
• If you depress the accelerator pedal  repeatedly to increase the engine 
speed while the engine is idling, the indicator comes on, and 
sometimes the steering wheel becomes harder to operate.
■What to do when th e indicator comes on
Stop the vehicle in a safe  place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle 
inspected by a dealer.
1 If the Brake System Indicator (Red) Comes On
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 and  ABS indicator come 
on simultaneously, the elec tronic brake distribution 
system is not working. Th is can result in vehicle 
instability under sudden braking.
Have your vehicle inspecte d by a dealer immediately.
If both red and amber brake system indicators come 
on, stop the vehicle in a  safe place and have it 
inspected by a dealer immediately.U.S.

moving the accelerator pedal. (Vehicle spee d may vary slightly; this is okay.) If you 
cannot do this for a continuous 90 seconds because of traffic conditions, drive for 
at least 30 seconds, then repeat it two mo re times (for a total of 90 seconds).
