Preparations For Jump Start
The battery in your vehicle is located in the
front of the engine compartment, behind the
left headlight assembly.Positive Battery Post NOTE:
Never use a fast battery charger to start the
engine, as this could damage the electronic
systems of your vehicle, particularly the igni
-
tion and engine fuel supply control units.
1. Apply the parking brake, shift the auto -
matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition OFF.
2. Turn off the heater, radio, and all unnec -
essary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the
jumper cables reach, apply the parking
brake and make sure the ignition is OFF.
Jump Starting Procedure
WARNING!
Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING! (Continued) 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.

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 for
a few minutes, and then start the engine
in the vehicle with the discharged
battery.
6. Once the engine is started, remove the jumper cables in the reverse sequence.
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 nega -
tive (-) 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 posi
-
tive (+) 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.
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.
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.

REFUELING IN EMERGENCY —
IF EQUIPPED

The fuel filling procedure in case of emer-
gency is described in the “Emergency Gas
Can Refueling”. Refer to “Refueling The
Vehicle” in “Starting And Operating” for
further information.
The vehicle is equipped with a refueling
funnel. If refueling is necessary, while using
an approved gas can, please insert the refu -
eling funnel into the filler neck opening.
Refueling Funnel Inserting Funnel
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your
engine by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the
transmission in NEUTRAL, but do not
increase engine idle speed.
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.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “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 the “H” and you hear
continuous chimes, turn the engine off
immediately and call for service.

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 reser-
voir and brake master cylinder, fill as
needed.
Check function of all interior and exterior
lights.
Control and recovery of additive level for
AdBlue® Diesel emissions (UREA) (if
equipped) At Each Oil Change
Change the engine oil filter.
Inspect the brake hoses and lines.
Inspect for the presence of water in the
fuel filter/water separator unit.
Inspect the CV/Universal joints.
Demanding Vehicle Use
Restore additive level for AdBlue® Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
