BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 234.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture.
For further information Ú
page 291.
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 291. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!

FRONT LOW/HIGH BEAM HEADLAMP —
MODELS WITH HIGH INTENSITY DISCHARGE
(HID) HEADLAMPS
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
key removed. 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
the 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.
FRONT/REAR SIDE MARKER LAMP
The Side Markers use LED lamps that are not
serviceable separately. The Side Markers must be
replaced as an assembly, see an authorized
dealer.
FRONT FOG LAMP
The Front Fog Lamps use LED sources that are not
serviceable separately. The Front Fog Lamp must
be replaced as an assembly; see an authorized
dealer.
FRONT TURN SIGNAL LAMPS
The Front Park/Turn function is part of the
headlamp assembly and use LED lamps that are
not serviceable separately. The headlamps must
be replaced as an assembly, see an authorized
dealer.
BACKUP LAMPS
The Backup Lamps use LED sources that are not
serviceable separately. The backup lamps must be
replaced as an assembly; see an authorized
dealer.
LICENSE LAMP
The License Lamp uses an LED source that is not
serviceable separately. The License Lamp must be
replaced as an assembly; see an authorized
dealer.
CENTER HIGH MOUNTED STOP LAMP (CHMSL)
The CHMSL Lamp uses LED sources that are not
serviceable separately. The CHMSL Lamp must be
replaced as an assembly; see an authorized
dealer.
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.
WARNING!
A transient high voltage occurs at the bulb
sockets of HID headlamps when the headlamp
switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced
properly. See an authorized dealer for service.

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.
