Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto-
matic 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 discharged 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
dangerous if done improperly Ú page 367.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds before
trying again.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.

Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc-
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper
fuel filler cap. A poorly fitting cap could let
impurities into the fuel system. Also, a poorly
fitting aftermarket cap can cause the Malfunc -
tion Indicator Light (MILyf W R L O O X P L Q D W H G X H W R
fuel vapors escaping from the system.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.4

In the ESC “Full Off” mode, the engine torque

Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer-

speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.

deadly. Follow the precautions below to prevent
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit in
a parked vehicle with the engine running for
an extended period. If the vehicle is stopped in
an open area with the engine running for more
than a short period, adjust the ventilation
system to force fresh, outside air into the
vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid the danger of
being hit when operating the jack or changing
the wheel.
Being under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on
you. You could be crushed. Never put any part
of your body under a vehicle that is on a jack.
If you need to get under a raised vehicle, take
it to a service center where it can be raised on
a lift.
Never start or run the engine while the vehicle
is on a jack.
The jack is designed to be used as a tool for
changing tires only. The jack should not be
used to lift the vehicle for service purposes.
The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.

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 clutch or
transmission failure during prolonged efforts
to free a stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE/SECOND gear and REVERSE,
do not spin the wheels faster than 15 mph
(24 km/hyf R U G U L Y H W U D L Q G D P D J H P D \ U H V X O W .
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/hyf
