negative (−) terminal of the good
battery. 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 the remote negative (−)
terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative (−) cable to the remote
negative (−) terminal, on the
vehicle with the dead battery. 10. Now start the vehicle with the
good battery and run the
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.
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.

Towing the Vehicle
Notice: Incorrectly towing a
disabled vehicle may cause
damage. The damage would not
be covered by the vehicle

Have the vehicle towed on a flatbed
car carrier or a wheel lift tow truck.
If a wheel lift tow truck is used, the
drive wheels cannot contact the
road while the vehicle is being
towed. A wheel dolly must be used
to lift all drive wheels off the ground.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing” in this
section.

If the vehicle has a hybrid engine,
see the hybrid manual for more

towing the vehicle behind another
vehicle –such as behind a motor
home. 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.

General Information
Your vehicle is an important
investment. This section describes
the required maintenance for the
vehicle. Follow this schedule to help
protect against major repair
expenses resulting from neglect or
inadequate maintenance. It may
also help to maintain the value of
the vehicle if it is sold. It is the
responsibility of the owner to have
all required maintenance performed.
Your dealer has trained technicians
who can perform required
maintenance using genuine
replacement parts. They have up‐to‐
date tools and equipment for fast
and accurate diagnostics. Many
dealers have extended evening and
Saturday hours, courtesy
transportation, and online
scheduling to assist with service
needs.
Your dealer recognizes the
importance of providing
competitively priced maintenance
and repair services. With trained technicians, the dealer is the place
for routine maintenance such as oil
changes and tire rotations and
additional maintenance items like
tires, brakes, batteries, and wiper
blades.
Notice:
Damage caused by
improper maintenance can lead to
costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids,
and lubricants are important to
keep the vehicle in good working
condition.
The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.
