94GETTING TO KNOW YOUR INSTRUMENT PANEL
Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capability
of charging system. The charging system is still
functioning properly.
Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior
lights, overloaded power outlets +12 Volts,
115 Volt AC, USB ports) during certain driving
conditions (city driving, towing, frequent stop -
ping).
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appliances
like vacuum cleaners, game consoles and
similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte
-
rior).
Check what may be plugged in to power
outlets +12 Volts, 115 Volt AC, USB ports.
Check HVAC settings (blower, temperature).
Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when applicable.
These indications are indicative and precautionary
and as such must not be considered as exhaustive.
Always refer to the information in this chapter in

320IN CASE OF EMERGENCY
PREPARATIONS FOR JUMP START
The battery in your vehicle is located in the front of
the engine compartment, behind the left headlight
assembly.

Battery Location

If you have a diesel engine, you may have two
batteries, however jump start off the driver side
battery.
The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to
gain access to the positive battery post. Do not
jump off fuses. Only jump directly off positive post
which has a positive (+) symbol on or around the
post.
NOTE:

1. Apply the parking brake, shift the automatic transmission into PARK and turn the ignition
OFF.

2. Turn off the heater, radio, and all 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
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
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!
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.

IN CASE OF EMERGENCY321
Connecting The Jumper Cables

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

NOTE:Do not jump off fuses. Only jump directly off
positive post.
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. A
“ground” is an exposed metallic/unpainted
part of the engine, frame or chassis, such as
an accessory bracket or large bolt. The ground
must be away from the battery and fuel
injection system.
Jump Starting Label

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 discon
-
necting procedure below.
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.
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.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
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.

340SERVICING AND MAINTENANCE
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 crosshatch
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 fluid reservoir is located under the hood and
should be checked for fluid level at regular
intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and
wipe the wiper blades clean. 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.
After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution used
with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid
line clogging, and is not harmful to paint or trim.
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.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's
charging system.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil 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 Úpage 320.
Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not
use a booster battery or any other booster
source with an output greater than 12 Volts.
Do not allow cable clamps to touch each
other.
Battery posts, terminals, and related accesso -
ries contain lead and lead compounds. Wash
hands after handling.
