uuCleaning uExterior Care
Maintenance
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.

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. Change the gear position to

3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
Vehicles with a compact spare tire
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.
