Replacing Exterior Bulbs
HIGH INTENSITY DISCHARGE (HID) HEAD -
LAMPS — IF EQUIPPED
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and the
ignition turned to the OFF position. Because of this,
you should not attempt to service a headlamp bulb yourself. If a headlamp bulb fails, take your vehicle
to an authorized dealer for service.
NOTE:
On vehicles equipped with HID headlamps, when
t h
e headlamps are turned on, there is a blue hue
to the lights. This diminishes and becomes more
white after approximately 10 seconds, as the
system charges.

electrical shock or electrocution if not serviced
properly. See an authorized dealer for service.

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

TIRES
TIRE SAFETY INFORMATION
Tire safety information will cover aspects of the
following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire Markings

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
s t
andard 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.

The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading,
road conditions, and posted speed limits)

SERVICING AND MAINTENANCE 227
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date code may only be on one side. Tires with white sidewalls will have the full TIN, including
the date code, located on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall tires as mounted on the vehicle. If the TIN is
not found on the outboard side, then you will find it on the inboard side of the tire.Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
XL = Extra load (or reinforced) tire, or
LL
= Light load tire or
C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load –
Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure –
Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
EXAMPLE:
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
This symbol certifies that the tire is in compliance with the US Department of Transportation tire safety standards and is approved for highway use
