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
Tow/haul is designed to assist while the vehicle is
pulling a large or heavy load or trailer. Tow/haul is
most useful while pulling such a load in rolling terrain,
in stop-and-go traffic, or when you need improved
low-speed control, such as when parking. The purpose
of the tow/haul mode is to:
•Reduce the frequency and improve the predictability
of transmission shifts,
•provide the same solid shift feel when pulling a heavy
load as when the vehicle is unloaded,
•improve control of vehicle speed while requiring less
throttle pedal activity.
Press this button located
to the right of the steering
wheel on the instrument
panel to turn tow/haul
mode on and off.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
G:Turn and Lane Change Signals.
53:Headlamp High/Low-Beam Changer.
N:Windshield Wipers.
L:Windshield Washer.
Flash-to-Pass Feature.
Information for these features is on the pages following.
Turn and Lane-Change Signals
G:An arrow on the instrument panel cluster flashes
in the direction of the turn or lane change.
To signal a turn, move the lever all the way up or down.
To signal a lane change, raise or lower the lever until
the arrow starts to flash. The turn signal automatically
flashes three times and if the tow-haul mode is active
it flashes six times. Holding the turn signal lever for
more than one second causes the turn signals to
flash continually until the lever is released.
The lever returns to its starting position when released.
If after signaling a turn or lane change the arrow
flashes rapidly or does not come on, a signal bulb
may be burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeFuses and Circuit Breakers on
page 5-105.
Turn Signal On Chime
If the turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime sounds at each flash of the turn signal
and the message TURN SIGNAL ON also appears in
the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-48. To turn off the chime
and message, move the turn signal lever to the
off position.
