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

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).

222SERVICING AND MAINTENANCE
(Continued)
Checking Oil Level
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every fuel stop. The best time to check the
engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the
low end of the range and MAX at the high end
of the range.
Crosshatched zone marked with dimples at
the MIN and the MAX ends of the range.
NOTE:
Always maintain the oil level within the cross -
hatch markings on the dipstick.
Adding 1 quart (1 liter) of oil when the reading is
at the low end of the dipstick range will raise the
oil level to the high end of the range marking.
Adding Washer Fluid
The windshield and rear window washers share
the same fluid reservoir. The fluid reservoir is
located in the front of the engine compartment.
Be sure to check the fluid level in the reservoir
at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator
antifreeze) and operate the system for a few
seconds to flush out the residual water.
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.Maintenance-Free Battery
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, and periodic maintenance is not
required.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water Ú page 204.
