Driving Information
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety Belts on
page 3‑13.
{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.

Driving and Operating 9-11
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 the 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).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑69.
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, 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 10‑89.

6.If your vehicle will be towing
a trailer, the load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how this
reduces the available cargo
and luggage load capacity
of your vehicle.
See Trailer Towing on page 9‑60
for important information on
towing a trailer, towing safety
rules, and trailering tips.

Driving and Operating 9-17
Vehicle speeds above
110 km/h (68 mph) should
be limited to five minutes
per use.
.Avoid making hard stops
for the first 322 km (200 mi)
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. SeeDriving
Characteristics and Towing
Tips on page 9‑56 for the
trailer towing capabilities
of your vehicle and more
information.
Following break‐in, engine
speed and load can be gradually
increased.
Ignition Positions
(Key Access)
The ignition switch has four different
positions.
Notice: Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer. The key must be fully extended to
start the vehicle.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (STOPPING THE ENGINE/
LOCK/OFF):
When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑24 for more information.
This is the only position from
which the key can be removed.
This locks the ignition and automatic
transmission.
Do not turn the engine off when the
vehicle is moving. This will cause
a loss of power assist in the brake
and steering systems and disable
the airbags.

Shifting Into Park
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow.
1. Hold the brake pedal down and set the parking brake.
See Parking Brake on page 9‑33
for more information.
2. Move the shift lever into P (Park) by pushing the lever all the way
toward the front of the vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running,
it could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running. If you have to leave the vehicle
with the engine running, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
down the regular brake pedal. See if
you can move the shift lever away
from P (Park) without first pulling it
toward you. If you can, it means that
the shift lever was not fully locked
into P (Park).
