Dinghy Towing
Two-Wheel Drive Vehicles
Notice:If the vehicle is towed
with all four wheels on the
ground, the drivetrain
components could be damaged.
The repairs would not be covered
by the vehicle warranty. Do not
tow the vehicle with all four
wheels on the ground.
Two-wheel-drive vehicles should not
be towed with all four wheels on the
ground. Two-wheel-drive
transmissions have no provisions
for internal lubrication while being
towed. Four-Wheel Drive Vehicles
Use the following procedure to
dinghy tow a four-wheel-drive
vehicle:
1. Position the vehicle being towed
behind the tow vehicle.
2. Put an automatic transmission in P (Park) or a manual
transmission in 1 (First).
3. Turn the engine off and firmly set the parking brake. See Parking
Brake on page 9‑44.
4. Securely attach the vehicle being towed to the tow vehicle.

Front Towing (Front Wheels Off
the Ground)–Four-Wheel-Drive
Vehicles
Use the following procedure to dolly
tow a four-wheel-drive vehicle from
the front:
1. Attach the dolly to the tow
vehicle following the dolly
manufacturer's instructions.
2. Drive the front wheels onto the dolly.
3. Put an automatic transmission in P (Park) or a manual
transmission in 1 (First). 4. Turn the engine off and firmly set
the parking brake. See Parking
Brake on page 9‑44.
{WARNING
Shifting a full‐time
four‐wheel‐drive vehicle's transfer
case into N (Neutral) can cause
the vehicle to roll even if the
automatic transmission is in
P (Park) or the manual
transmission is in any gear. You
or others could be injured. Make
sure the parking brake is firmly
set before the transfer case is
shifted to N (Neutral).
5. Secure the vehicle to the dolly following the manufacturer's
instructions.
6. Shift the transfer case to N (Neutral). See “Shifting into
N (Neutral)” underFour-Wheel
Drive on page 10‑30. 7. Release the parking brake only
after the vehicle being towed is
firmly attached to the towing
vehicle.
8. Turn the ignition to LOCK/OFF.
After towing, see “Shifting Out of
N (Neutral)” underFour-Wheel Drive
on page 10‑30.
If the vehicle being towed will not be
started or driven for six weeks or
more, remove the battery cable from
the negative terminal (post) of the
battery to prevent the battery from
draining.

Recommended Fuel on
page 9‑51.
{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do the
work. SeeDoing Your Own
Service Work on page 10‑4. At your dealer, you can be certain
that you will receive the highest
level of service available. Your
dealer has specially trained service
technicians, uses genuine
replacement parts, as well as,
up‐to‐date tools and equipment to
ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids and
Lubricants on page 11‑6 and
Maintenance Replacement Parts on
page 11‑9. We recommend the use
of genuine parts from your dealer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
12 000 km/7,500 miles. See Tire
Rotation on page 10‑60.
Scheduled
Maintenance
When the Change Oil Message
Displays
Change engine oil and filter. See
Engine Oil on page 10‑9. An
Emission Control Service.
When the CHANGE OIL message
displays, service is required for the
vehicle as soon as possible, within
the next 1 000 km/600 miles.
If driving under the best conditions,
the engine oil life system might not
indicate the need for vehicle service
for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your dealer has
trained service technicians who will
perform this work and reset the
system. If the engine oil life system
is reset accidentally, service the
vehicle within 5 000 km/3,000 miles
since the last service. Reset the oil

.Four‐wheel drive only: Transfer
case fluid change (severe
service) for vehicles mainly
driven when frequently towing a
trailer, or used for taxi, police,

hose at transfer case for kinks
and proper installation. Check to
be sure vent hose is
unobstructed, clear, and free of
debris. During any maintenance,
if a power washer is used to
clean mud and dirt from the
underbody, care should be taken
to not directly spray the transfer
case output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.

Emission Control Service. The
U.S. Environmental Protection
Agency or the California Air
Resources Board has
determined that the failure to
perform this maintenance item
will not nullify the emission
warranty or limit recall liability
prior to the completion of the
vehicle's useful life. We,
however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded. First Engine Oil Change After
