WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Note:Some Warning Lights are reconfigurable telltale (RTT) indicator
lights and will illuminate in the Message Center Display and function the
same as the warning light.
Service engine soon:The
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, theService engine soonlight will stay on until the
engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds theService engine soonlight blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for Inspection/Maintenance (I/M) testingin the
Maintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could

damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Powertrain malfunction/reduced
power (RTT) (if equipped):
Displays when the engine has
defaulted to a ’limp-home’ operation.
Report the fault to a dealer at the
earliest opportunity.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

Low tire pressure warning:
Illuminates when your tire pressure is
low. If the light remains ON at start
up or while driving, the tire pressure
should be checked. Refer toInflating
Your Tiresin theTires, Wheels and Loadingchapter. When the ignition
is first turned to ON, the light will illuminate for 3 seconds to ensure the
bulb is working. If the light does not turn ON or begins to flash, have the
system inspected by your authorized dealer. For more information on this
system, refer toUnderstanding Your Tire Pressure Monitoring System
in theTires, Wheels and Loadingchapter.
Low fuel (RTT) (if equipped):
Displays when the fuel level in the
fuel tank is at or near empty (refer
toFuel gaugein this chapter).
Check fuel cap (RTT)
(if equipped):Displays when the
fuel cap may not be properly
installed. Continued driving with
this light on may cause the Service
engine soon warning light to come
on. Refer toFuel filler capin theMaintenance and Specifications
chapter.
Low washer fluid (RTT)
(if equipped):Displays when the
windshield washer fluid is low.
O/D off:Illuminates when the
overdrive function of the
transmission has been turned off,
refer to theDrivingchapter. If the
light flashes steadily or does not illuminate, have the transmission
serviced soon, or damage may occur.
AdvanceTrac(RTT)
(if equipped):Displays when the

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The ignition should be in the OFF position while the vehicle is being
refueled. When the gauge first indicates empty, there is a small amount
of reserve fuel in the tank. When refueling the vehicle from empty
indication, the amount of fuel that can be added will be less than the
advertised capacity due to the reserve fuel.
The FUEL icon and arrow indicates which side of the vehicle the fuel
filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
by your authorized dealer as soon as possible.
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between “L” and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine oil level. Add oil if needed. If the oil
level is correct, have your vehicle checked by your authorized dealer.

To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
BRAKES
Your service brakes are self-adjusting. Refer to thescheduled
maintenance informationfor scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.

If the parking brake fails to release
after completing this procedure, use
the manual parking brake release
lever.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
ADVANCETRACWITH ROLL STABILITY CONTROL(RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
The AdvanceTracwith RSC system provides stability enhancement
features such as Roll Stability Control(RSC), Electronic Stability
Control (ESC) and Traction Control (TCS) for certain driving situations.
The system includes an AdvanceTracwith RSC on/off button, and a
“sliding car” icon in the instrument cluster.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTracwith RSC performs a system self-check. During
AdvanceTracwith RSC operation you may experience the following:
•A rumble, grunting, or grinding noise after startup and when driving
off
•A slight deceleration of the vehicle
•The AdvanceTracwith RSC indicator light will flash when the system
is activated.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
Traction Control
Traction Control helps your vehicle maintain traction, when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and/or applying the anti-lock brakes. Traction Control is a driver
aid that helps your vehicle.

•Driving on slick surfaces.
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
Roll Stability Control(RSC)
The RSC system works in conjunction with the AdvanceTracsystem to
help maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
During Roll Stability Control(RSC) events the “sliding car” icon in the
instrument cluster will flash momentarily.
Driving conditions that may activate AdvanceTracwith RSC include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTracwith RSC button and icon functionality
The AdvanceTracwith RSC system automatically turns on each time the
engine is started, even if it was turned off when the engine was last shut
down. The “sliding car” icon which is located with the warning lights in the
instrument cluster will illuminate during bulb check at initial start-up and
then go off. This tells you that the system is normal and active. All
functions of the AdvanceTracwith RSC (RSC, ESC, Engine Traction
Control, and Brake Traction Control) will be activated at start up. When
the system is left active, the “sliding car” icon will flash only when any of
the components of the system are affecting the vehicle’s performance,
otherwise the light will remain off. Consequently, the “sliding car” icon will
not be illuminated during most of your normal driving.
The AdvanceTracwith RSC button,
located on the center stack of the
instrument panel, allows the driver
to control certain features of the
AdvanceTracwith RSC system
below 25 mph (40 km/h). If the
vehicle is below 25 mph (40 km/h), momentarily pressing the
AdvanceTracwith RSC button will disable RSC, ESC and Engine
Traction Control and steadily illuminate the “sliding car” icon. Pressing
and holding the AdvanceTracwith RSC button for more than five
seconds will further disable the brake portion of the Traction Control
feature and the “sliding car” icon will flash momentarily and then
illuminate steady.

Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a AdvanceTracwith
RSC event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
If a failure is detected in the AdvanceTracwith RSC system, and the
AdvanceTracwith RSC button has not been pushed, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced by an authorized dealer immediately.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds

Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
If your vehicle is equipped with AdvanceTracwith RSC, press the
AdvanceTracwith RSC button (refer toAdvanceTracwith Roll
Stability Control (RSC) Stability Enhancement Systemin this
chapter) while driving in deep sand if you experience excessive engine
power reduction.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even four–wheel drive vehicles can lose traction in
slick mud. As when you are driving over sand, apply the accelerator
slowly and avoid spinning your wheels. If the vehicle does slide, steer in
the direction of the slide until you regain control of the vehicle.
If the transmission, transfer case, front axle or rear axle are submerged
in water, their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
