FUSES
WARNING!
• When replacing a blown fuse, always use
an appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-

tem), power unit systems (engine sys-
tem, transmission system) or steering
system blows, contact an authorized
dealer.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.

Preparations For Jacking
CAUTION!
Always lift or jack the vehicle from the
correct jacking points. Failure to follow
this information could cause damage to
the vehicle or underbody components.
NOTE:
To assist with changing a spare tire, the air
suspension system (if equipped) has a fea-
ture which allows the automatic leveling to
be disabled.
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side
of the vehicle closest to moving traffic,
pull far enough off the road to avoid being
hit when operating the jack or changing
the wheel.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.4. Place the gear selector into PARK.
5. Turn the ignition OFF.
6. Block both the front and rear of the wheel
diagonally opposite of the jacking posi-
tion. For example, if changing the right
front tire, block the left rear wheel.
NOTE:
Passengers should not remain in the ve-
hicle when the vehicle is being jacked.7. For vehicles equipped with Quadra-Lift,
refer to “Quadra-Lift — If Equipped” in
“Starting And Operating” in the Owner’s
Manual for further information on dis-
abling automatic leveling.
Jacking Instructions
WARNING!
Carefully follow these tire changing warn-
ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface as
far from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the
wheel to be raised.
• Apply the parking brake firmly and set
the transmission in PARK.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when
it is on a jack.
• Do not get under the vehicle when it is
on a jack. If you need to get under a

Jack Usage Precautions
To complete the Use and Maintenance Hand-
book to which this supplement is attached,
given below are some instructions on the
proper use of the jack.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause inju-
ries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
CAUTION!
models or different things, is strictly pro-
hibited. Never use it to carry out mainte-
nance or repairs under the vehicle or to
change summer/winter wheels and vice
versa. Never go under the raised vehicle. If
any work under the vehicle is necessary,
contact an authorized dealer. Incorrect
placing of the jack can cause the vehicle to
drop: use it only in the positions indicated.
Do not use the jack for loads higher than
that specified on the label. Never start the
engine with vehicle raised. If the vehicle is
raised more than necessary, everything
can become more unstable, with the risk of
the vehicle dropping violently. Therefore
raise the vehicle only as much as neces-
sary for the wheel/spare.
Maintenance
• Make sure grime does not build up on the
“worm screw.”
• Keep the “worm screw” lubricated.• Never modify the jack.
Conditions Of Non-Use:
• Temperatures below −40°C.
• On sandy or muddy ground.
• On uneven ground.
• On steep roads.
• In extreme weather conditions: thunder-
storms, typhoons, hurricanes, blizzards,
storms, etc.
JUMP STARTING
If your vehicle has a discharged battery it can
be jump started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly so
please follow the procedures in this section
carefully.
