The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
15. Anti-Lock Brake (ABS) LightThis light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four
seconds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is turned to the ON/RUN position, have the light
inspected by an authorized dealer.
16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear
driveshafts are mechanically
locked together forcing the front
and rear wheels to rotate at the
same speed. Low range provides a greater
gear reduction ratio to provide increased
torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation — If Equipped” in “Starting
And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder The fuel pump symbol points to the
side of the vehicle where the fuel
door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel
tank when the ignition switch is in the ON/RUN
position.
20. Electronic Vehicle Information Center
(EVIC) White Telltale Area
This area will display the EVIC reconfigurable
white telltales. For further information refer to
“Electronic vehicle Information Center (EVIC)”.
21. Electronic Vehicle Information Center
(EVIC) Amber Telltale Area
This area will display the EVIC reconfigurable
amber caution telltales. For further information
refer to “Electronic vehicle Information Center
(EVIC)”.
22. Electronic Vehicle Information Center
(EVIC) Red Telltale Area
This area will display the EVIC reconfigurable
red telltales. For further information refer to
“Electronic vehicle Information Center (EVIC)”.

When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving

When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to
check for damage. That way you can get any
problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your
vehicle. Check tires, body structure, steer-
ing, suspension, and exhaust system for
damage.
• Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness,
particularly on the chassis, drivetrain com-
ponents, steering, and suspension. Re-
tighten them, if required, and torque to the
values specified in the Service Manual. •
Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the ra-
diator, fan, brake rotors, wheels, brake lin-
ings, and axle yokes inspected and cleaned
as soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking power
when you need it to prevent a collision. If you
have been operating your vehicle in dirty
conditions, get your brakes checked and
cleaned as necessary.
• If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material. Im-
pacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
POWER STEERING
3.6L Engine and 3.0L Diesel Engine
Your vehicle is equipped with an electro-
hydraulic power steering system that will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will vary its assist to provide light efforts while
parking and good feel while driving. If the
electro-hydraulic power steering system expe-
riences a fault that prevents it from providing
power steering assist, then the system will
provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop
power steering assistance in order to prevent
damage to the system. Normal operation will
resume once the system is allowed to cool.
If the “SERVICE POWER STEER-
ING SYSTEM” message and a
flashing icon are displayed on the
EVIC screen, it indicates that the
vehicle needs to be taken to the

Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% Ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 10% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using Ethanol-
blended fuels, due to the lower energy content
of Ethanol.
Problems that result from using Methanol/
gasoline or E85 Ethanol blends are not the
responsibility of the manufacturer. While MTBE
is an oxygenate made from Methanol, it does
not have the negative effects of Methanol.
CAUTION!
Use of fuel with Ethanol content higher than
10% may result in engine malfunction, starting
and operating difficulties and materials degra-
dation. These adverse effects could result in
permanent damage to your vehicle.Clean Air Gasoline
Many gasolines are now being blended that
contribute to cleaner air, especially in those
areas where air pollution levels are high. These
new blends provide a cleaner burning fuel and
some are referred to as “reformulated gaso-
line.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT in Gasoline
MMT is a manganese containing metallic addi-
tive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emission system
performance in some vehicles. The manufac-
turer recommends that gasoline without MMT
be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline
pump; therefore, you should ask your gasoline
retailer whether or not his/her gasoline contains
MMT. Materials Added to Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have
these additives will help improve fuel economy,
reduce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-
ents. These can harm fuel system gasket and
diaphragm materials.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:

2. Open the fuel filler door, and remove the fuel
filler cap.
CAUTION!
•Damage to the fuel system or emission
control system could result from using an
improper fuel cap (gas cap). A poorly fitting
