7. Connect one end of the blacknegative (–) cable to the
negative (–) terminal of the good
battery (C). Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (–)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (–) terminal
on the vehicle with the dead
battery.
8. Connect the other end of the black negative (–) cable to an
unpainted heavy metal engine
part (D) away from the dead
battery, but not near engine
parts that move. 9. Start the engine in the vehicle
with the good battery and run
the engine at idle speed for at
least four minutes.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.
Notice: If the jumper cables 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 correct
order, making sure that the
cables do not touch each other or
other metal.

.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.
Dinghy Towing from the Front
(With 2.0L Engine and
Automatic Transmission)
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.
Vehicles with the 2.0L engine and
an automatic transmission should
not be towed with all four wheels on
the ground.
Dinghy Towing from the Front
(All Except 2.0L Engine and
Automatic Transmission)
When dinghy towing a vehicle with
an automatic transmission, 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.
Use the following procedure to
dinghy tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle being towed behind the tow vehicle.
2. Shift the automatic transmission to P (Park) or a manual
transmission into 1 (First) gear
and turn the engine off.
3. Set the parking brake.
4. Following the manufacturer's instructions, attach the vehicle
being towed to the tow vehicle.
5. Shift the automatic transmission to N (Neutral) or a manual
transmission to Neutral.
6. Release the parking brake.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
be done when the tow vehicle is
parked.

{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. See Doing 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 11‑8. 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 mi. See Tire
Rotation on page 10‑55.
Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oil on page 10‑9. 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. 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 life
