RECOVERY TOWING
ACCESSING THE FRONT TOWING
POINT
WARNING: Using recovery hooks
is dangerous and should only be done by
a person familiar with proper vehicle
recovery safety practices. Improper use
of recovery hooks may cause hook failure
or separation from the vehicle and could
result in serious injury or death. WARNING:
Slowly remove the
slack from the recovery strap prior to
pulling. Failure to do so can introduce
significantly higher loads which can
cause the recovery hooks to break off, or
the recovery strap to fail which can cause
serious injury or death. WARNING:
Never link two straps
together with a clevis pin. These heavy
metal objects could become projectiles
if the strap breaks and can cause serious
injury or death. WARNING:
Switch the ignition off
before removing the recovery hook.
Failure to do so could result in personal
injury. WARNING: The recovery hook can
become hot. Let the recovery hook cool
down before removing it. Failure to do
so could result in personal injury.
Your vehicle has frame-mounted front
recovery hooks.
Note: Do not apply a load to the recovery
hooks that is greater than the gross vehicle
weight rating of your vehicle. Before using recovery hooks:
•
Make sure all attaching points are
secure and capable of withstanding
the applied load.
• Do not use chains, cables or tow straps
with metal hook ends.
• Only use recovery straps that have a
minimum breaking strength two to
three times the gross vehicle weight of
the stuck vehicle.
• Make sure the recovery strap is in good
condition and free of visible cuts, tears
or damage.
• Use a damper device such as a tarp,
heavy blanket or piece of carpet, and
place it over the recovery strap to help
absorb the energy in the event the
strap breaks.
• Make sure the stuck vehicle is not
loaded heavier than its gross vehicle
weight rating specified on the
certification label.
• Align the tow vehicle and stuck vehicle
in a straight line, within 10 degrees.
• Keep bystanders to the sides of the
vehicle, at a distance of at least twice
the length of the recovery strap. This
helps avoid injury from the hazard of a
recovery hook or strap breaking, or a
vehicle lurching into their path.

TRANSPORTING THE VEHICLE
If you need to tow your vehicle, contact a
professional towing service or your
roadside assistance service provider.
Your manufacturer produces a towing
manual for all authorized tow truck
operators. Have your tow truck operator
refer to this manual for proper hook-up
and towing procedures.
We recommend the use of a wheel lift and
dollies or flatbed equipment to tow your
vehicle. Vehicle damage could occur if
towed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehicles
must have their designated drive wheels
off the ground regardless of towing
direction. Use tow dollies to prevent
damage to the transmission. All-wheel or four-wheel drive vehicles
require that all wheels be off the ground
using a wheel lift and dollies or flatbed
equipment. This prevents damage to the
transmission and drive system.

TOWING YOUR VEHICLE
PRECAUTIONS
Use the following guidelines when towing
your vehicle. Failure to follow this
instruction could result in vehicle damage
not covered by the vehicle warranty.
Note:
Make sure you properly secure your
vehicle to the tow vehicle.
Note: If you are unsure of the vehicle ’s
configuration, contact an authorized dealer.
RECREATIONALLY TOWING
YOUR VEHICLE - 4X4 WARNING: Do not disconnect the
battery when recreationally towing your
vehicle. This prevents the transfer case
from shifting properly and could cause
the vehicle to roll, even if the
transmission is in park (P). WARNING:
Placing the transfer
case in its neutral position could cause
your vehicle to freely roll. Make sure you
press and hold the brake pedal and the
vehicle is in a secure, safe position when
you place the transfer case in its neutral
position.
Follow these guidelines if you have a need
for recreational towing. An example of
recreational towing would be towing your
vehicle behind a motorhome. These
guidelines are to make sure that you do
not damage the transmission. You can only tow your vehicle with all
wheels on the ground by placing the
transfer case in its neutral position and
engaging the recreational tow feature.
Perform the following steps after
positioning your vehicle behind the tow
vehicle and properly securing them
together.
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
Note: Failure to put the transfer case in its
neutral position can damage vehicle
components.
Note: You can check the towing status at
any time by opening the driver door or
turning the ignition to the accessory or on
position. Neutral Tow Enabled Leave
Transmission in Neutral
