Braking
SeeBrake System Warning Light on
page 4-22.
Braking action involves perception
time and reaction time. Deciding
to push the brake pedal is
perception time. Actually doing
it is reaction time.
Average reaction time is about
three-fourths of a second. But that
is only an average. It might be less
with one driver and as long as two or
three seconds or more with another.
Age, physical condition, alertness,
coordination, and eyesight all play
a part. So do alcohol, drugs,
and frustration. But even in
three-fourths of a second, a vehicle
moving at 100 km/h (60 mph) travels
20 m (66 ft). That could be a lot of
distance in an emergency, so
keeping enough space between
the vehicle and others is important.And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or icy;
tire tread; the condition of the brakes;
the weight of the vehicle; and the
amount of brake force applied.
Avoid needless heavy
braking. Some people drive
in spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic. This
is a mistake. The brakes might not
have time to cool between hard
stops. The brakes will wear out much
faster with a lot of heavy braking.
Keeping pace with the traffic and
allowing realistic following distances
eliminates a lot of unnecessary
braking. That means better braking
and longer brake life.If the engine ever stops while
the vehicle is being driven, brake
normally but do not pump the brakes.
If the brakes are pumped, the pedal
could get harder to push down. If the
engine stops, there will still be some
power brake assist but it will be used
when the brake is applied. Once the
power assist is used up, it can take
longer to stop and the brake pedal
will be harder to push.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories
and Modi cations on page 9-3.
8-4 Driving and Operating
Regularly inspect the driveshaft/
propshaft couplings and halfshaft
boots for cracking or grease leakage.
It is not recommended that the
vehicle be used for ongoing race
track/competitive driving.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in
a quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they actually ride on the
water. This can happen if the road
is wet enough and you are going
fast enough. When your vehicle
is hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
•Allow extra following distance.
•Pass with caution.
•Keep windshield wiping
equipment in good shape.
•Keep the windshield washer fluid
reservoir filled.
•Have good tires with proper tread
depth. SeeTires on page 9-48.
•Turn off cruise control.
8-8 Driving and Operating
WARNING (Continued)
•Fully open the air outlets on
or under the instrument panel.
•Adjust the Climate Control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control System
in the Index.
For more information about carbon
monoxide, seeEngine Exhaust on
page 8-25.
Snow can trap exhaust gases
under your vehicle. This can cause
deadly CO (carbon monoxide) gas
to get inside. CO could overcome
you and kill you. You cannot see it
or smell it, so you might not know
it is in your vehicle. Clear away
snow from around the base of
your vehicle, especially any that
is blocking the exhaust.Run the engine for short periods
only as needed to keep warm,
but be careful.
To save fuel, run the engine for only
short periods as needed to warm the
vehicle and then shut the engine off
and close the window most of the
way to save heat. Repeat this until
help arrives but only when you feel
really uncomfortable from the cold.
Moving about to keep warm also
helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help with
the headlamps. Do this as little as
possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn
the traction system off and use
the rocking method.
{WARNING
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be injured.
The vehicle can overheat, causing
an engine compartment fire or
other damage. Spin the wheels as
little as possible and avoid going
above 55 km/h (35 mph) as shown
on the speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 9-68.
Driving and Operating 8-11
Rocking the Vehicle to
Get it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth between
R (Reverse) and a forward gear,
or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on
the accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 9-87.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory-installed options.
Two labels on the vehicle
show how much weight it
may properly carry, the Tire
and Loading Information label
and the Certification label.{WARNING
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR), or
either the maximum front or
rear Gross Axle Weight Rating
(GAWR). If you do, parts on
the vehicle can break, and
it can change the way your
vehicle handles. These could
cause you to lose control and
crash. Also, overloading can
shorten the life of the vehicle.
8-12 Driving and Operating
A (LOCK/OFF):This is the only
position from which the key can be
removed. This locks the steering
wheel, ignition and automatic
transmission.
On vehicles with an automatic
transmission, the shift lever must
be in P (Park) to turn the ignition
switch to the LOCK/OFF position.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to
ACC/ACCESSORY. If this does not
work, then the vehicle needs service.
B (ACC/ACCESSORY):This
position provides power to some of
the electrical accessories. It unlocks
the steering wheel and ignition. The
transmission is also unlocked in this
position on automatic transmission
vehicles. To move the key from
ACC/ACCESSORY to LOCK/OFF,
push in the key and then turn it to
LOCK/OFF.C (ON/RUN):The ignition switch
stays in this position when the engine
is running. This position can be used
to operate the electrical accessories,
including the ventilation fan and
12 volt power outlet, as well as to
display some warning and indicator
lights.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
D (START):This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened if the ignition
is still in ACC/ACCESSORY and the
key is in the ignition.Key Lock Release
This vehicle is equipped with an
electronic key lock release system.
The key lock release is designed
to prevent ignition key removal
unless the shift lever is in P (Park).
The key lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery. If the vehicle has an
uncharged battery or a battery with
low voltage, try charging or jump
starting the battery. SeeJump
Starting on page 9-84.

One to Four Shift Light
Message (V8 Only)
When this message comes on,
you can only shift from 1 (First) to
4 (Fourth) instead of 1 (First) to
2 (Second). The message will be
displayed in the Driver Information
Center.You must complete the shift into
4 (Fourth) to turn off this feature.
This helps you get the best possible
fuel economy.
After shifting to 4 (Fourth), you may
downshift to a lower gear if you
prefer.
Notice:Forcing the shift lever
into any gear except 4 (Fourth)
when the 1 TO 4 SHIFT message
comes on may damage the
transmission. Shift only from
1 (First) to 4 (Fourth) when the
message comes on.
This message will come on when:•The engine coolant temperature
is higher than 76°C (169°F),
•The vehicle is going 24 to
31 km/h (15 to 19 mph) and
•The vehicle is at 21 percent
throttle or less.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 4-23. Driver Information Center
Driving and Operating 8-31
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling,
the computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can
help the driver steer around
the obstacle while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls braking
pressure accordingly.Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
antilock work. The antilock pump
or motor might be heard operating,
and the brake pedal might be felt to
pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
To apply the parking brake, pull
up on the parking brake handle.
It is not necessary to push in on
the release button while applying
the parking brake. If the ignition is
in the ON/RUN position, the brake
system warning light will come on.
SeeBrake System Warning Light
on page 4-22.
8-32 Driving and Operating
To release the parking brake:
1. Hold the brake pedal down.
2. Pull the parking brake handle up
until you can press the release
button.
3. Hold the release button in as you
move the brake handle all the
way down.
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature wear
or damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.Driving with the parking brake
applied will cause a warning chime to
sound and the Park Brake message
to appear in the DIC. The message
will remain on until:
•the parking brake is released
•the vehicle comes to a stop.
If you are towing a trailer and you
are parking on a hill, seeDriving
Characteristics and Towing Tips
on page 8-49.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brakecontrol module to supplement
the power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle.
The stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsations or
pedal movement during this time
is normal and the driver should
continue to apply the brake pedal
as the driving situation dictates
The Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly decreased.
