23. Charging System Light
This light shows the status of the electrical charging
system. The light should come on when the ignition
switch is first turned ON and remain on briefly as a bulb
check. If the light stays on or comes on while driving, turn
off some of the vehicle’s non-essential electrical devices or
increase engine speed (if at idle). If the charging system
light remains on, it means that the vehicle is experiencing
a problem with the charging system. Obtain SERVICE
IMMEDIATELY. See an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
24. Low Fuel Warning Light When the fuel level reaches approximately 2.3 U.S.
Gallons (8.7 Liters) this light will come on and
remain on until fuel is added. The Low Fuel
Warning Light may turn on and off again, especially
during and after hard braking, accelerations, or turns.
This occurs due to the shifting of the fuel in the tank.

Extreme Cold Weather (Below20°F or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.

the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to “Jump Start-

JACKING AND TIRE CHANGING
Run Flat Tires
This vehicle is equipped with run flat tires. Although the
tires are designed with a “run flat” feature that allows the
vehicle to be driven approximately 50 miles (80 km) at
55 mph (88 km/h). immediate service should be ob-
tained.
WARNING!
Do not exceed 50 mph (80 km/h) if the “Tire Pressure
Monitoring Telltale Light” is illuminated. Vehicle
handling and braking may be reduced. You could
have an accident and be severely or fatally injured.
NOTE: The “run flat” feature eliminates the need for a
spare tire and jack. This vehicle is not equipped with
either a spare tire or jack.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack
follow the manufacturer ’s operating instructions and
precautions.
CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
304 WHAT TO DO IN EMERGENCIES

WARNING!
When temperatures are below the freezing point,
electrolyte in a discharged battery may freeze. Do not
attempt jump-starting because the battery could rup-
ture or explode and cause personal injury. Battery
temperature must be brought above freezing point
before attempting a jump-start.
Preparations for Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.

WARNING!
•Take care to avoid the radiator cooling fan when-
ever 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 watch bands or
bracelets that might 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.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories. 3. If using a another vehicle to jump-start the battery,
park the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in per-
sonal injury or property damage due to battery ex-
plosion.
