Make sure that the jack lift head
is in the correct position or you
may damage your vehicle. The
repairs would not be covered by
your warranty.
6. Position the jack lift head at thejack location nearest the
flat tire.
7. Set the jack to the necessaryheight. Position it directly below
the jacking position so it does
not slip.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and

the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only

changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper

Storing the Compact Spare Tire
and Tools
Reverse the instructions for
removing the spare tire and tools to
store the compact spare tire.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi). Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the AWD (if equipped), ABS, and
Traction Control systems may
engage until the spare tire is
recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.
Caution
Tire chains will not fit the compact
spare. Using them can damage
the vehicle and the chains. Do not
use tire chains on the compact
spare.

The jump start negative grounding
point (1) for the discharged battery
is the engine block or an engine
mounting bolt. Connect to a spot as
far away from the discharged
battery as possible.
The jump start positive terminal (2)
on the discharged battery is in the
engine compartment on the driver
side of the vehicle.
The jump start negative terminal (3)
and positive terminal (4) are on the
battery of the vehicle providing the
jump start.
The positive jump start connection
for the discharged battery is under a
trim cover. Open the cover to
expose the terminal.
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in
P (Park) with an automatic
transmission, or Neutral with a
manual transmission.
Caution

be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting. 4. Turn the ignition off. Turn off all
lights and accessories in both
vehicles, except the hazard
warning flashers if needed.
{Warning

Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
