engine for a while.
11. Try to start the vehicle that had the dead battery. If it will
not start after a few tries, it
probably needs service.

are connected or removed in
the wrong order, electrical
shorting may occur and damage
the vehicle. The repairs would
not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the

10-88 Vehicle Care
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. Re-install
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). 6. To prevent the battery from
draining while the vehicle is
being towed, remove the 15 amp
ECM fuse and the 50 amp
BATT1 fuse from the underhood
fuse block and store in a
safe location. See Engine
Compartment Fuse Block on
page 10‑33.
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.

11-2 Service and Maintenance
{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

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 11‑7 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 10‑52.
Scheduled
Maintenance
When the Change Engine Oil

See Engine Oil on page 10‑8.
An Emission Control Service.
When the CHANGE ENGINE
OIL SOON 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.
