Insert the power plug into the vehicle power
outlet socket. Start the vehicle engine.
Push the Tire Service Kit power button on. The
electric compressor will be turned on, sealant
and air will inflate the tire.
Minimum 26 psi (1.8 bar) of pressure should be
reached within 20 minutes. If the pressure has
not been reached, turn off and remove the Tire
Service Kit, drive the vehicle 30 feet
(10 meters) back and forth, to better distribute
the sealant inside the tire.
Attach the clear flexible filling tube of the
compressor directly to the tire valve and repeat
the inflation process.
When the correct pressure has been reached,
start driving the vehicle to uniformly distribute
the sealant inside the tire. After 10 minutes,
stop and check the tire pressure. If the pressure
is below 19 psi (1.3 bar), do not drive the
vehicle, as the tire is too damaged, contact the
nearest authorized dealer.WARNING!
Do not attempt to seal a tire on the side of
the vehicle closest to traffic. Pull far enough
off the road to avoid the danger of being hit
when using the Tire Service Kit.
Do not use Tire Service Kit or drive the
vehicle under the following circumstances:
If the puncture in the tire tread is
approximately 1/4 inch (6 mm) or
larger.
If the tire has any sidewall damage.
If the tire has any damage from driving
with extremely low tire pressure.
If the tire has any damage from driving
on a flat tire.
If the wheel has any damage.
If you are unsure of the condition of the
tire or the wheel.
Keep Tire Service Kit away from open
flames or heat source.
A loose Tire Service Kit thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
Tire Service Kit in the place provided.
Failure to follow these warnings can result
in injuries that are serious or fatal to you,
your passengers, and others around you.
Take care not to allow the contents of Tire
Service Kit to come in contact with hair,
eyes, or clothing. Tire Service Kit sealant is
harmful if inhaled, swallowed, or absorbed
through the skin. It causes skin, eye, and
respiratory irritation. Flush immediately
with plenty of water if there is any contact
with eyes or skin. Change clothing as soon
as possible, if there is any contact with
clothing.
Tire Service Kit Sealant solution contains
latex. In case of an allergic reaction or rash,
consult a physician immediately. Keep Tire
Service Kit out of reach of children. If swal -
lowed, rinse mouth immediately with plenty
of water and drink plenty of water. Do not
induce vomiting! Consult a physician imme -
diately.

Jump Starting Procedure

Jumper Cable Connections

Connecting The Jumper Cables

1. Connect the positive
(+) end of the jumper
cable to the positive (+)
post of the
discharged vehicle.

2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) end of the jumper
cable to the negative (-) post of the booster
battery. 4. Connect the opposite end of the negative
(-)
jumper cable to a good engine ground
(exposed metal part of the discharged
vehicle’s engine) away from the battery and
the fuel injection system.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, follow the disconnecting procedure below.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged vehicle.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause the
battery to explode and could result in
personal injury. Only use the specific ground
point, do not use any other exposed metal
parts.

21_VM_OM_EN_USC_t.book Page 206

IN CASE OF EMERGENCY207
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the negative (-) jumper cable from the
negative (-) post of the booster battery.

3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.

4. Disconnect the opposite end of the positive (+) jumper cable from the
positive (+) post of the vehicle with the
discharged battery.

If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
the engine idle speed while preventing
vehicle motion with the brakes. NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.7

gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
CAUTION!
It is advisable to contact an authorized dealer
to have the reinstall procedure carried out. If
you would like to proceed in performing the
reinstall procedure special attention must be
paid to the correct coupling of the clips.
Otherwise damage to the cover or noise
might be heard due to incorrect fastening of
the lower cover.

Gear Selector Override Access Hole

6. The vehicle may then be started in NEUTRAL (N).
7. Reinstall the gear selector boot.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE (D)
and REVERSE (R), while gently pressing the
accelerator. Use the least amount of
accelerator pedal pressure that will maintain
the rocking motion, without spinning the wheels
or racing the engine.
NOTE:
Shifts between DRIVE (D) and REVERSE (R) can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE (D) or REVERSE (R).
7

21_VM_OM_EN_USC_t.book Page 209

210IN CASE OF EMERGENCY
NOTE:
Push the ESC OFF switch, to place the Electronic
Stability Control (ESC) system in Partial Off
mode, before rocking the vehicle Ú page 146.
Once the vehicle has been freed, push the ESC
OFF switch again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will
minimize overheating and reduce the risk of
transmission failure during prolonged efforts
to free a stuck vehicle.
CAUTION!
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, extended engine idle
time, extremely hot or cold ambient
temperatures will influence when the “Oil
Change Required” message is displayed.
Severe Operating Conditions can cause the
change oil message to illuminate as early as
3,500 miles (5,600 km) since last reset. Have
your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, to reset the message
Úpage 46. NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
350 hours of engine run time or 12 months,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Vehicles that are operated in a dusty and
off-road environment, or predominately at idle
or very low engine RPM are known as Severe
Duty vehicles. It is recommended that you
change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
Check the fluid levels of the coolant reservoir
and brake master cylinder, fill as needed.
Check function of all interior and exterior
lights.
Maintenance Plan
Refer to the maintenance schedule for the
required maintenance intervals. More frequent
maintenance may be needed in severe
conditions, such as dusty areas and very short
trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.
