TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.

PREPARATIONS FOR JACKING

1. Park the vehicle on a firm, level surface as far from the edge of the roadway as
possible. Avoid icy or slippery areas.

2. Turn on the Hazard Warning Flashers.
3. Apply the parking brake.
4. Place the gear selector into PARK (automatic transmission) or FIRST gear
(manual transmission).
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite the jacking position. For
example, if the driver’s front wheel is being
changed, block the passenger’s rear wheel.

Wheel Blocked

NOTE:
Passengers should not remain in the vehicle
when the vehicle is being lifted or raised.
JACKING AND CHANGING A TIRE
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic, pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
Turn on the Hazard Warning Flashers.
Apply the parking brake firmly and place an
automatic transmission in PARK; a manual
transmission in REVERSE or FIRST gear.
Block the wheel diagonally opposite the
wheel to be raised.
Never start or run the engine with the
vehicle on a jack.
Do not let anyone sit in the vehicle when it
is on a jack.
Do not get under the vehicle when it is on a
jack. If you need to get under a raised
vehicle, take it to a service center where it
can be raised on a lift.

JUMP STARTING PROCEDURE
Remote Positive (+) Post
Remote Negative (-) Post
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact. You
could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.

IN CASE OF EMERGENCY231
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. For
vehicles with automatic transmission, push and
hold the lock button on the gear selector. Then
shift back and forth between DRIVE and
REVERSE (with automatic transmission) or
FIRST gear and REVERSE (with manual
transmission), while gently pressing the
accelerator. Use the least amount of
accelerator pedal pressure that will maintain
the rocking motion, without spinning the wheels
or racing the engine.
NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or
less. Whenever the transmission remains in
NEUTRAL for more than two seconds, you must
press the brake pedal to engage DRIVE or
REVERSE. NOTE:
Push the ESC OFF switch (if necessary), to place
the Electronic Stability Control (ESC) system in
“Partial Off” mode, before rocking the vehicle.
Refer to “Electronic Brake Control System” in
“Safety” for further information. Once the
vehicle has been freed, push the ESC OFF
switch again to restore “ESC On” mode.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will
minimize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer
than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
When “rocking” a stuck vehicle by shifting
between DRIVE / FIRST gear and REVERSE,
do not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may
result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

IN CASE OF EMERGENCY233
REAR-WHEEL DRIVE (RWD) MODELS
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed. If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
flat towed (with all four wheels on the ground)
under the following conditions:
The transmission must be in NEUTRAL. Refer
to "Manual Park Release" in this section for
instructions on shifting the automatic trans
-
mission to NEUTRAL when the engine is off.
The towing distance must not exceed
30 miles (48 km).
The towing speed must not exceed 30 mph
(48 km/h).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
then the only acceptable method of towing is
with a flatbed truck.
