5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires require higher inflation pressure than the other
tires.
6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts, bulges or
other irregularities.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or damage to your tires. If your vehicle
seems to pull to one side, vibrate or shake when you’re driving, the
wheels may be out of alignment. Have a qualified technician at a
reputable repair facility check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a reputable repair facility. Front wheel drive (FWD) vehicles, and
those with independent front suspension require alignment of all four
wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Service Maintenance Guide that comes with your vehicle) will help your
tires wear more evenly providing better tire performance and longer tire
life. Unless otherwise specified, rotate the tires approximately every
8,000 km (5,000 miles).

air filter element may result in severe engine damage. The customer
warranty may be voided for any damage to the engine if the correct air
filter element is not used.
2Refer to Vehicle Emissions Control Information (VECI) decal for spark
plug gap information.

the same cylinder. If a spark plug needs to be replaced, use only spark
plugs with the service part number suffix letter as shown on the engine
decal.

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your dealer for specific weight
information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems—such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
