CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
(Continued)
WARNING!(Continued)
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
12. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition

•Anti-Lock Brake (ABS)
This light will turn on when the ABS system is
not functioning and service is required. If the
ABS light is on the brake system should be
serviced as soon as possible.
•Malfunction Indicator Light (MIL)
This light will turn on when certain conditions
exist. The vehicle should be serviced if the light
stays on through several driving cycles.
•Electronic Stability Control (ESC)
If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine
running, a malfunction has been detected in
the ESC system.

This light indicates the Electronic Stability Con-
trol (ESC) is off.

This light will turn on to indicate that one or
more doors may be ajar.

This telltale indicates low engine oil pressure. If
the light turns on while driving, stop the vehicle and shut
off the engine as soon as possible. A chime will sound
when this light turns on.

If one or more tires have low pressure, “Inflate Tire To
XX” is displayed with the vehicle ICON and the tire
pressure values in each corner of the ICON with the
pressure value of the low tire displayed in a different
color than the other tire pressure values.
If the Tire Pressure system requires service, “Service Tire
Pressure System” is displayed.
Tire Pressure is an information only function and cannot
be reset.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16” (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced. Refer
to “Replacement Tires” in this section for further infor-
mation.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
•Distance driven
•Performance tires, tires with a speed rating of V or
higher, and summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for

Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE: Under no circumstances should oil change in-
tervals exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first.
