current vehicle status. Some telltales are optional
and may not appear.

RED WARNING LIGHTS
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if
the driver’s seat belt is unbuckled, a
chime will sound and the light will turn
on. When driving, if the driver or front passenger

MAR/ON/RUN position. If the light is
either not on during startup, stays on, or turns
on while driving, have the system inspected at
an authorized dealer as soon as possible. This
light will illuminate with a single chime when a
fault with the Air Bag Warning Light has been
detected, it will stay on until the fault is cleared.
If the light comes on intermittently or remains
on while driving, have an authorized dealer
service the vehicle immediately.
Battery Charge Warning Light
This warning light will illuminate when
the battery is not charging properly. If
it stays on while the engine is running,
there may be a malfunction with the
charging system. Contact an authorized dealer

204IN CASE OF EMERGENCY
See below steps to prepare for jump starting:

1. Apply the parking brake, shift the
automatic transmission into PARK (P) and
turn the ignition to the OFF position.

2. Turn off the heater, radio, and all electrical accessories.
3. Pull upward and remove the protective cover over the remote positive (+) battery
post.
4. 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
Connecting The Jumper Cables

Jumper Cable Connections

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

NOTE:

The remote positive (+) post is located in the
engine compartment on the driver's side under
the cover of the Front Power Distribution Center.

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.

21_VF_OM_EN_USC_t.book Page 204

IN CASE OF EMERGENCY205
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
the fuel injection system.
NOTE:
The remote negative (-) post is located in the
front of the engine compartment on the driver's
side. 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.
Disconnecting The Jumper Cables

1. Disconnect the negative end
(-) of the
jumper cable from the remote negative (-)

post 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 remote
positive (+) post of the discharged vehicle. 5. Close the cover of the Front Power Distri
-
bution Center.
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!
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.
