NOTE:Removal of the air cleaner filter housing may be
necessary prior to replacing bulbs in the headlamp
assembly on the driver side of the vehicle.
2. Remove the large dust cap from the headlamp housing by turning it counterclockwise.
3. Turn the bulb counterclockwise, and remove.
Headlamp Location

4. Disconnect the bulb from the socket assembly and install the replacement bulb.
5. Reinstall the bulb and socket assembly into the headlamp assembly, and then turn it
clockwise. 6. Reinstall the access cap making sure it is
seated into the housing and turn cap
clockwise to engage locking lugs. Visually, you
should be unable to see the blue O-ring gasket.
The access cap should be uniformly seated
and you should not be able to pull the access
cap off without turning it counterclockwise.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
CAUTION!
If the access cap is not installed correctly after
bulb replacement, the lamp becomes
susceptible to dust, condensation, and water
intrusion. This may ultimately lead to an
inoperative lamp. If the access cap cannot be
installed correctly, please return to an
authorized dealer for proper repair or access
cap replacement if necessary.

Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on Euro -
pean design standards. Tires designed to this
standard have the tire size molded into the side -
wall beginning with the section width. The letter
"P" is absent from this tire size designation.
Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based on
US design standards. The size designation for
LT-Metric tires is the same as for P-Metric tires
except for the letters “LT” that are molded into
the sidewall preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
High flotation tire sizing is based on US design
standards and it begins with the tire diameter
molded into the sidewall.
Example: 31x10.5 R15 LT.
