23. Anti-Lock Brake (ABS) LightThis light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is placed in 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,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional 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 placed in the ON/RUN position, have
the light inspected by an authorized dealer.
24. Low Fuel Light This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank. 25. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when
the ignition is in the ON/RUN position before engine
start. If the MIL does not come on when turning the key
from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. Refer to “Jump Starting” in
“What To Do In Emergencies” for further informa-
tion.
Automatic Transmission – If Equipped
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
246 STARTING AND OPERATING

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering

STARTING AND OPERATING 271

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the “Brake Warning Light.”
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF) the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Anti-Lock Brake System (ABS) — If Equipped
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
The Electronic Brake Force Distribution (EBD) prevents
the rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
276 STARTING AND OPERATING

You also may experience the following when the brake
system goes into anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•The clicking sound of solenoid valves,
•Brake pedal pulsations, and
•A slight drop or fall away of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
WARNING!
•The Anti-Lock Brake System (ABS) contains so-
phisticated electronic equipment that may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting
equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop. (Continued)

STARTING AND OPERATING 277

WARNING! (Continued)
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition
of the vehicle brakes and tires or the traction
afforded.
•The Anti-Lock Brake System (ABS) cannot prevent
collisions, including those resulting from exces-
sive speed in turns, following another vehicle too
closely, or hydroplaning.
•The capabilities of an Anti-Lock Brake System
(ABS) equipped vehicle must never be exploited
in a reckless or dangerous manner, that could
jeopardize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Warning Light
The “Anti-Lock Brake System (ABS) Warning
Light” monitors the Anti-Lock Brake System. The
light will come on when the ignition switch is turned to
the ON position and may stay on for as long as four
seconds.
If the “ABS Warning Light” remains on or comes 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 Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
278 STARTING AND OPERATING

Traction Control System (TCS) – If Equipped
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system functions similar to a
limited-slip differential (LSD) and controls the wheel
spin across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“Partial Off” mode. Refer to “ESP (Electronic Stability
Program)” in this section for more information.
Brake Assist System (BAS) – If Equipped
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking
situation by sensing the rate and amount of brake appli-
cation and then applies optimum pressure to the brakes.
This can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
280 STARTING AND OPERATING

WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.5
STARTING AND OPERATING 323

WARNING! (Continued)
•Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and
allow enough slack for turning corners.(Continued)
WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. Always, block or \bchock\b
the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. Max loading as defined on the “Tire and Load-
ing Information” placard.
2. GTW
3. GAWR
(Continued)
330 STARTING AND OPERATING

WARNING! (Continued)
4. Tongue weight rating for the trailer hitch utilized.
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for the proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes

Donot interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
