2 (Second):This position reduces vehicle speed even
more than 3 (Third) without using the brakes. You can
use 2 (Second) on hills. It can help control vehicle speed
as you go down steep mountain roads, but then you
would also want to use the brakes off and on.
You may use this feature for reducing torque to the rear
wheels when you are trying to start the vehicle from a
stop on slippery road surfaces.
1 (First):This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in 1 (First) while the vehicle is
moving forward, the transmission will not shift into first
gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair
will not be covered by the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on a
hill, use the brakes to hold the vehicle in place.Tow/Haul Mode
Vehicles with an automatic transmission have 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.
Turn the tow/haul mode on and off by pressing the
button, located to the right of the steering wheel on
the instrument panel. When tow/haul is on, a light on the
instrument panel cluster will come on.

SeeTow/Haul Mode Light on page 4-36for more
information.
Also see “Tow Haul Mode” underTowing a Trailer on
page 5-26for more information.
Grade Braking (Six Speed Automatic
Transmission)
The Grade Braking shift modes can be activated by
pressing the tow/haul button on the dash. While
in Range Selection Mode, Grade Braking is deactivated
allowing the driver to select a desired range of gears.
Grade Braking is only active while the Tow/Haul Mode is
selected and you are not in the Range Selection Mode.
See “Tow/Haul Mode listed previously andAutomatic
Transmission Operation (Six Speed Automatic
Transmission) on page 3-26orAutomatic Transmission
Operation (Four Speed Automatic Transmission) on
page 3-31for more information on the Range Selection
Mode. Grade Braking assists in maintaining desired
vehicle speeds when driving on downhill grades by
automatically shifting to lower gears when the driver
desires to slow the vehicle by applying the brake.
This reduces wear on the braking system and increases
control of the vehicle.
Also seeTowing a Trailer on page 5-26for more
information.
Cruise Grade Braking
(Six Speed Automatic Transmission)
Cruise Grade Braking operates only while cruise
control is engaged in Tow/Haul mode. Cruise Grade
Braking assists in maintaining desired vehicle speeds
when driving on downhill grades in cruise control by
automatically shifting to lower gears when the cruise
set speed is exceeded.
While in the Range Selection Mode (RSM) mode, cruise
grade braking is not available.
SeeAutomatic Transmission Operation (Six Speed
Automatic Transmission) on page 3-26orAutomatic
Transmission Operation (Four Speed Automatic
Transmission) on page 3-31.

Parking Brake
To set the parking brake, hold the regular brake pedal,
then push down the parking brake pedal.If the ignition is on, the brake system warning light will
come on.
To release the parking brake, hold the regular brake
pedal down. Pull the handle, located just above
the parking brake pedal, with the parking brake symbol,
to release the parking brake.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on a hill, see
Towing a Trailer on page 5-26.

Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake or
shift to a lower gear to keep the vehicle’s speed
down. When the brakes are applied the cruise control
turns off.
Ending Cruise Control
There are three ways to end cruise control:
•Step lightly on the brake pedal.
•Press the[button on the steering wheel.
•Press theIbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
Exterior Lamps
The exterior lamps control is located on the instrument
panel to the left of the steering wheel.
It controls the following systems:
•Headlamps
•Taillamps
•Parking Lamps
•License Plate Lamps
•Instrument Panel Lights

The vehicle can be only driven for a short time with the
reading in either warning zone. If it must be driven,
turn off all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking,
both need to work.
If the warning light comes on, there could be a brake
problem. Have the brake system inspected right away.
This light should come on briefly when ignition key is
turned to ON/RUN. If it does not come on, have it fixed
so it will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. See
Parking Brake on page 3-35for more information. The
light stays on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push, or
the pedal might go closer to the floor. It could take
longer to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 5-22.
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
