Dodge Durango (DN). Manual — part 3

TOWING RECOMMENDATIONS

A vehicle equipped with SAE approved wheel lift-

type towing equipment can be used to tow all vehi-
cles. When towing a 4WD vehicle using a wheel-lift
towing device, use tow dollies under the opposite end
of the vehicle. A vehicle with flatbed device can also
be used to transport a disabled vehicle (Fig. 2).

SAFETY PRECAUTIONS

CAUTION: The following safety precautions must
be observed when towing a vehicle:

• Secure loose and protruding parts.

• Always use a safety chain system that is inde-

pendent of the lifting and towing equipment.

• Do not allow towing equipment to contact the

disabled vehicle’s fuel tank.

• Do not allow anyone under the disabled vehicle

while it is lifted by the towing device.

• Do not allow passengers to ride in a vehicle

being towed.

• Always observe state and local laws regarding

towing regulations.

• Do not tow a vehicle in a manner that could

jeopardize the safety of the operator, pedestrians or
other motorists.

• Do not attach tow chains, T-hooks, or J-hooks to

a bumper, steering linkage, drive shafts or a non-re-
inforced frame hole.

• Do not tow a heavily loaded vehicle. Use a flat-

bed device to transport a loaded vehicle.

GROUND CLEARANCE

CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums or rotors.

A towed vehicle should be raised until lifted wheels

are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain or steep rises in the road.

RAMP ANGLE

If a vehicle with flatbed towing equipment is used,

the approach ramp angle should not exceed 15
degrees.

TOWING WHEN KEYS ARE NOT AVAILABLE

When the vehicle is locked and keys are not avail-

able, use a flat bed hauler. A wheel-lift device can be
used on 4WD vehicles provided all the wheels are
lifted off the ground using tow dollies.

TWO-WHEEL-DRIVE VEHICLE TOWING

Chrysler Corporation recommends that a vehicle be

towed with the rear end lifted, whenever possible.

WARNING: WHEN TOWING A DISABLED VEHICLE
AND THE DRIVE WHEELS ARE SECURED IN A
WHEEL LIFT OR TOW DOLLIES, ENSURE THE
TRANSMISSION IS IN THE PARK POSITION (AUTO-
MATIC TRANSMISSION) OR A FORWARD DRIVE
GEAR (MANUAL TRANSMISSION).

WARNING: ENSURE VEHICLE IS ON A LEVEL SUR-
FACE OR THE WHEELS ARE BLOCKED TO PRE-
VENT VEHICLE FROM ROLLING.

TWO WHEEL DRIVE TOWING-REAR END LIFTED

CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.

2WD vehicles can be towed with the front wheels

on the surface for extended distances at speeds not
exceeding 48 km/h (30 mph).

(1) Attach wheel lift device to rear wheels.
(2) Place the transmission in neutral.
(3) Raise vehicle to towing position.
(4) Attach safety chains. Route chains so not to

interfere with tail pipe when vehicle is lifted.

(5) Turn the ignition switch to the OFF position to

unlock the steering wheel.

CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.

(6) Secure steering wheel in straight ahead posi-

tion with a clamp device designed for towing.

(7) Place transmission in park.

TWO WHEEL DRIVE TOWING-FRONT END LIFTED

CAUTION: Many vehicles are equipped with air
dams, spoilers, and/or ground effect panels. To
avoid component damage, a wheel-lift towing vehi-
cle or a flat-bed hauling vehicle is recommended.

CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.

(1) Attach wheel lift device to rear wheels.
(2) Place the transmission in neutral.
(3) Raise the rear of the vehicle off the ground and

install tow dollies under rear wheels.

(4) Attach wheel lift device to front wheels and

raise vehicle to towing position.

(5) Attach the safety chains.
(6) Turn the ignition switch to the OFF position to

unlock the steering wheel.

(7) Secure steering wheel in straight ahead posi-

tion with a clamp device designed for towing.

(8) Place transmission in park.

FOUR-WHEEL-DRIVE VEHICLE TOWING

Chrysler Corporation recommends that a vehicle be

transported on a flat-bed device. A Wheel-lift device
can be used provided all the wheels are lifted off
the ground using tow dollies.

WARNING: WHEN TOWING A DISABLED VEHICLE
AND THE DRIVE WHEELS ARE SECURED IN A
WHEEL LIFT OR TOW DOLLIES, ENSURE THE
TRANSMISSION IS IN THE PARK POSITION.

CAUTION: Many vehicles are equipped with air
dams, spoilers, and/or ground effect panels. To
avoid component damage, a wheel-lift towing vehi-
cle or a flat-bed hauling vehicle is recommended.

FOUR WHEEL DRIVE TOWING—REAR END LIFTED

WARNING: ENSURE VEHICLE IS ON A LEVEL SUR-
FACE OR THE WHEELS ARE BLOCKED TO PRE-
VENT VEHICLE FROM ROLLING.

(1) Attach wheel lift device to front wheels.
(2) Place the transmission in neutral.
(3) Raise the front of the vehicle off the ground

and install tow dollies under front wheels.

(4) Attach wheel lift device to rear wheels and

raise vehicle to towing position.

(5) Attach safety chains to frame rails. Route

chains so not to interfere with tail pipe when vehicle
is lifted.

(6) Turn the ignition switch to the OFF position to

unlock the steering wheel.

CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.

(7) Secure steering wheel in straight ahead posi-

tion with a clamp device designed for towing.

(8) Place the transmission in park.

FOUR WHEEL DRIVE TOWING—FRONT END
LIFTED

WARNING: ENSURE VEHICLE IS ON A LEVEL SUR-
FACE OR THE WHEELS ARE BLOCKED TO PRE-
VENT VEHICLE FROM ROLLING.

(1) Attach wheel lift device to rear wheels.
(2) Place the transmission in neutral.
(3) Raise the rear of the vehicle off the ground and

install tow dollies under rear wheels.

(4) Attach wheel lift device to front wheels and

raise vehicle to towing position.

(5) Attach the safety chains.

CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.

(6) Turn the ignition switch to the OFF position to

unlock the steering wheel.

(7) Secure steering wheel in straight ahead posi-

tion with a clamp device designed for towing.

FLOOR JACK

CAUTION: Do not attempt to lift a vehicle with a
floor jack positioned under:

•

An axle tube.

•

Aluminum differential.

•

A body side sill.

•

A steering linkage component.

•

DESCRIPTION AND OPERATION

EXHAUST SYSTEM

DESCRIPTION

CAUTION: Avoid

application

of

rust

prevention

compounds or undercoating materials to exhaust
system floor pan exhaust heat shields. Light over-
spray near the edges is permitted. Application of
coating will result in excessive floor pan tempera-
tures and objectionable fumes.

The gasoline engine exhaust system consists of

engine exhaust manifolds, exhaust pipes, catalytic

converter(s), extension pipe (if needed), exhaust heat
shields, muffler and exhaust tailpipe (Fig. 1).

The exhaust system must be properly aligned to

prevent stress, leakage and body contact. Minimum
clearance between any exhaust component and the
body or frame is 25.4 mm (1.0 in.). If the system con-
tacts any body panel, it may amplify objectionable
noises from the engine or body.

OPERATION

The exhaust system channels exhaust gases from

the engine and away from the vehicle.
