Jacking up the vehicle and removing
the damaged tire
WARNING
.Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle on
other vehicles. The jack is designed
for lifting only your vehicle during a
tire change.
. Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack. .
Do not start or run the engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip
differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.SCE0875
Jack-up point
1. Place the jack directly under the jack-up points as illustrated.
The jack should be used on level firm
ground.

SCE0876
2. Loosen each wheel nut one or two turnsby turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.
NCE130
3. Install the assembled jack rod into the
jack as shown.
4. Carefully raise the vehicle until the clearance between the tire and ground
is achieved.
5. To lift the vehicle, securely hold the jack lever and rod with both hands and turn
the jack lever.
NOTE:
Before jacking up the vehicle, make sure the
ignition switch is placed in the OFF position.
If the vehicle is lifted up with the engine
running, the auto-leveling suspension will
become disabled after 120 seconds. To
reset the auto-leveling suspension, cycle

Installing the spare tire
The full-size temporary use only spare tire
(if so equipped) is designed for emergency
use. (See specific instructions under the
heading “Wheels and tires” (P.8-27).)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
,,,,,)
until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel nut wrench, tighten the wheel
nuts securely in the sequence as illu-
strated. Lower the vehicle completely.
WARNING
.
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque: 98 ft-lb (133 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.

COLD pressure:
After the vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver side center
pillar.
After adjusting tire pressure to the COLD
tire pressure, the display of the tire pressure
information may show higher pressure than
the COLD tire pressure after the vehicle has
been driven more than 1 mile (1.6 km). This is
because the tire pressurizes as the tire
temperature rises. This does not indicate a
system malfunction.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
4. Close the liftgate.
WARNING
. Always make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an accident or sudden stop.
. The full-size temporary use only
spare tire (if so equipped) is designed
for emergency use. (See specific in-
structions under the heading “Wheels
and tires” (P.8-27).) To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
.
If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
. Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles or
