Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the power steering uid reservoir.
3. Plug the cord into a normal, grounded
110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.

When in the MANUAL MODE (M) a number will
display next to the M, indicating the current gear
that has been selected. The number displayed in
the gear indicator is the highest gear that can be
used. However, your vehicle can automatically shift
to lower gears as it adjusts to driving conditions.
This means that all gears below that number are
available. When FIFTH (5) is selected, FIRST (1)
through FIFTH (5) gears are automatically shifted
by the vehicle, but SIXTH (6) cannot be used until
the plus/minus button located on the steering
column lever is used to change to the gear.
The DSC controls the vehicle and engine speed
while driving down a hill or towing a trailer, by
allowing you to select a desired range of gears.
The transmission will prevent a gear range until a
speed that is appropriate for current driving
conditions is achieved. If shifting is prevented for
any reason, the currently selected gear will
ash multiple times in the instrument panel cluster.
Grade Braking is not available when the Driver
Shift Control is active. SeeTow/Haul Mode
on page 150for more information.
While using the DSC, Cruise Control and the
Tow/Haul mode can be used.Tow/Haul Mode
Your vehicle has a tow/haul mode. The tow/haul
mode adjusts the transmission shift pattern to
reduce shift cycling, providing increased
performance, vehicle control, and transmission
cooling when towing or hauling heavy loads.

They also let police know you have a problem.
Your front and rear turn signal lamps will ash on
and off.
The hazard warning
asher button is located
on top of the steering
column.
The hazard warning ashers work no matter what
ignition position the key is in, and even if the
key is not in the ignition.
Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
When the hazard warning ashers are on, your

Other Warning Devices
If you carry reective triangles, you can set
them up at the side of the road about 300 feet
(100 m) behind your vehicle.
Horn
To sound the horn, press the center pad on the
steering wheel.

Tilt Wheel
Your vehicle has a tilt wheel, that lets you adjust
the steering wheel before driving. Raising it to
the highest level gives more room to exit and enter
your vehicle.
The tilt steering wheel lever is located on the
lower left side of the column.
To tilt the wheel, hold the steering wheel and pull
the lever. Then move the steering wheel to a
comfortable position and release the lever to lock
the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).When you apply your brakes, cruise control is
turned off.
If your vehicle has the StabiliTrak
®system and
begins to limit wheel spin while you are using
cruise control, the cruise control will automatically
disengage. SeeStabiliTrak
®System on
page 349. When road conditions allow you to
safely use it again, you may turn the cruise
control back on.
The cruise control
buttons are located
on left side of the
steering wheel.
