354 Vehicle Care
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Use only a flatbed tow truck for
towing a disabled vehicle. Never
use a sling type lift or damage will
occur. Use ramps to help reduce
approach angles if necessary.
A towed vehicle should have its
drive wheels off the ground.
Consult a professional towing
service if the disabled vehicle must
be towed.
Front Attachment Points
The vehicle is equipped with
specific attachment points to be
used by the towing provider. These
holes may be used to pull the
vehicle from a flat road surface onto
the flatbed tow truck.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle, such as behind a motor
home. The two most common types
of recreational vehicle towing are known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly.
Here are some important things to
consider before recreational vehicle
towing:
.
The towing capacity of the
towing vehicle. Be sure to read
the tow vehicle manufacturer's
recommendations.
. How far the vehicle will be
towed. Some vehicles have
restrictions on how far and how
long they can tow.
. The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
. If the vehicle is ready to be
towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
Dinghy Towing (2.5L L4
Engine)
This vehicle was not designed or
intended to be dinghy towed.
Dinghy Towing (3.6L
V6 Engine)
If the vehicle is front-wheel drive, it
can be dinghy towed from the front.
These vehicles may also be towed
by putting the front wheels on a
dolly. See“Dolly Towing” later in this
section.
If the vehicle is all-wheel drive, it
can be dinghy towed from the front.
These vehicles can also be towed
by placing them on a platform trailer
with all four wheels off of the
ground. These vehicles cannot be
towed using a dolly. For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle that will be towed and secure it to the
towing vehicle.
2. Remove the shift lever boot bypulling up on the rear of the
trim plate.

3. Use a small screwdriver or toolto press and hold the manual
release button on the rear right.
4. Put the vehicle in N (Neutral).
Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission could be
damaged. Be sure to follow all
steps of the dinghy towing
procedure prior to and after
towing the vehicle.
Caution
If 105 km/h (65 mph) is exceeded
while towing the vehicle, it could
be damaged. Never exceed
105 km/h (65 mph) while towing
the vehicle. Once the destination has been
reached:
1. Shift the vehicle to P (Park).
2. Reinstall the shift lever boot by inserting the front edge and
pressing the rear of the trim
plate until it snaps into place.
3. Start the engine and let it idle for more than three minutes
before driving the vehicle.
Caution
Too much or too little fluid can
damage the transmission. Be
sure that the transmission fluid is
at the proper level before towing
with all four wheels on the
ground.
Caution
Do not tow a vehicle with the front
drive wheels on the ground if one
of the front tires is a compact

spare tire. Towing with two
different tire sizes on the front of
the vehicle can cause severe
damage to the transmission.
Dolly Towing (All-Wheel-Drive
Vehicles)
All-wheel-drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground.
