Driving Information
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
your safety belt. See Safety Belts on
page 3‑12.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
(Continued)
WARNING (Continued)
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{WARNING
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious —or even
fatal —collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.

New Vehicle Break-In
Notice:The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
.Keep your speed at
88 km/h (55 mph) or less for
the first 805 km (500 miles).
.Do not drive at any one
constant speed, fast or
slow, for the first 805 km
(500 miles). Do not make
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.Avoid making hard stops for
the first 322 km (200 miles) or
so. During this time the new
brake linings are not yet
broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get
new brake linings.
.Do not tow a trailer during
break-in. See
Trailer Towing
on page 9‑79 for the trailer
towing capabilities of the
vehicle and more
information.
Following break‐in, engine speed
and load can be gradually
increased.
Adjustable Throttle and
Brake Pedal
On vehicles with this feature, you
can change the position of the
throttle and brake pedals.

Driving and Operating 9-41
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle. D (Drive):
This position is for
normal driving. It provides the best
fuel economy for the vehicle. If you
need more power for passing, and
you are:
.Going less than about 55 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
D (Drive) can be used when towing
a trailer, carrying a heavy load,
driving on steep hills, or for off-road
driving. You may want to shift the
transmission to a lower gear
selection if the transmission shifts
too often.
Downshifting the transmission in
slippery road conditions could result
in skidding, see “Skidding”under
Loss of Control on page 9‑6. When temperatures are very cold,
the Hydra-Matic
®automatic
transmission's gear shifting may be
delayed providing more stable shifts
until the engine warms up. Shifts
may be more noticeable with a cold
transmission. This difference in
shifting is normal.
M (Manual Mode): This position
lets drivers select the range of gears
appropriate for current driving
conditions. See “Range Selection
Mode” underManual Mode on
page 9‑42
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.

Driving and Operating 9-43
Range Selection Mode 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.
Grade Braking is not available when
the Range Selection Mode is active.
SeeTow/Haul Mode on page 9‑43
for more information.
While using the Range Selection
Mode, Cruise Control and the
Tow/Haul Mode can be used.
Tow/Haul Mode
The 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 while towing or
hauling heavy loads.
Press the button located on the end
of the shift lever to turn the tow/haul
on or off. While the tow/haul is on, a
light on the instrument panel cluster
comes on.
See
Tow/Haul Mode Light on
page 5‑24 for more information.

Selection Mode. See
“Tow/Haul Mode” listed
previously and Manual Mode on
page 9‑42 for more information on
the Range Selection Mode. Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades by automatically
implementing a shift schedule that
utilizes the engine and transmission
to slow the vehicle. This reduces
wear on the braking system and
increases control of the vehicle.
Grade Braking monitors vehicle
speed, acceleration, engine torque
and brake pedal usage. Using this
information, it detects when the
truck is on a downhill grade and the
driver desires to slow the vehicle by
pressing the brake.
Cruise Grade Braking
Cruise Grade Braking assists
when driving on a downhill grade.
It maintains vehicle speed by
automatically implementing a shift
schedule that uses the engine and
the transmission to slow the vehicle.

the parking brake is still on.
If you are towing a trailer and are
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑75.
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 brake
control 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 pulsation 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.

Continuous Damping
Control (CDC)
This vehicle may have a continuous
damping control system called
Autoride
®. With this feature,
improved vehicle ride and handling
is provided under a variety of
passenger and loading conditions.
Autoride is fully automatic
and uses a computer controller to
continuously monitor vehicle speed,
wheel to body position, lift/dive,
and steering position of the
vehicle. The controller then sends
signals to each shock absorber
to independently adjust the damping
level to provide the optimum
vehicle ride. Autoride also interact with the tow/
haul mode that, when activated, will
provide additional control of the
shock absorbers. This additional
control results in better ride and
handling characteristics when the
vehicle is loaded or towing a trailer.
See
“Tow/Haul Mode” underTrailer
Towing on page 9‑79 for more
information.
Automatic Level Control
The automatic level control rear
suspension is available on light‐duty
vehicles and comes as a part of the
Continuous Damping Control (CDC)
suspension, if equipped.
This type of level control is fully
automatic and will provide a better
leveled riding position as well as
better handling under a variety of
passenger and loading conditions. An air compressor connected to the
rear shocks will raise or lower the
rear of the vehicle to maintain
proper vehicle height. The system is
activated when the ignition key is
turned to ON/RUN and will
automatically adjust vehicle height
thereafter. The system may exhaust
(lower vehicle height) for up to
ten minutes after the ignition key
has been turned off. You may hear
the air compressor operating when
the height is being adjusted.
If a weight‐distributing hitch is being
used, it is recommended to allow
the shocks to inflate, thereby
leveling the vehicle prior to adjusting
the hitch.
