If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highesttemperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to N (Neutral); otherwise,
shift to the highest gear while
driving —D (Drive) or L (Low).
If the temperature overheat gauge
is no longer in the overheat zone or
an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slow
for about 10 minutes. Keep a safe
vehicle distance from the car in front
of you. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away. If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates firing groups of cylinders
helps prevent engine damage. In this mode, there is a significant
loss in power and engine
performance. The temperature
gauge indicates an overheat
condition exists. Driving extended
distances and/or towing a trailer in
the overheat protection mode
should be avoided.
Notice:
After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair.
The engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil
and reset the oil life system.
See Engine Oil on page 10‑8.

Towing the Vehicle
Notice:To avoid damage, the
disabled vehicle should be towed
with all four wheels off the
ground. Care must be taken with
vehicles that have low ground
clearance and/or special
equipment. Always flatbed on
a car carrier.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
See Roadside Assistance Program
(U.S. and Canada) on page 13‑8 or
Roadside Assistance Program
(Mexico) on page 13‑10.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing” in
this section.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a
motorhome. 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:.What is the towing capacity
of the towing vehicle?
Be sure to read the tow
vehicle manufacturer's
recommendations.
.What is the distance that will
be travelled? Some vehicles
have restrictions on how far and
how long they can tow.
.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

Vehicle Care 10-83
Dinghy Towing
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. Reinstall
the fuse to start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be
towed, shift the transmission to
P (Park), and turn the ignition
to LOCK/OFF.
2. Secure the vehicle to the towing vehicle.
3. Set the parking brake.
4. Turn the ignition to ACC/ACCESSORY.
5. Shift the transmission to N (Neutral).

50 amp BATT1 fuse from the
underhood fuse block and store

Compartment Fuse Block on
page 10‑31.
7. Release the parking brake.
Notice: 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.
Notice: 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 is reached:

2. Reinstall the fuses in the
underhood fuse block.

LOCK/OFF and remove the key
from the ignition.
4. Disconnect the vehicle from the towing vehicle.
Notice: 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 or dinghy towed
from the front.
