the engine and clutch systems. Any attempt
to shift into lower gear with clutch pedal
pressed may result damage to the clutch
system. Shifting into lower gear and
releasing the clutch may result in engine
damage.

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
“Malfunction 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 “Malfunction Indicator Light

Water ingestion into the axles, transmis-
sion, transfer case, engine or vehicle inte -
rior can occur if you drive too fast or
through too deep of water. Water can cause
permanent damage to engine, driveline or
other vehicle components, and your brakes
will be less effective once wet and/or
muddy.
When driving through water, do not exceed
5 mph (8 km/hyf $ O Z D \ V F K H F N Z D W H U G H S W K

In the ESC “Full Off” mode, the engine
torque reduction and stability features are
disabled. Therefore, enhanced vehicle
stability offered by the ESC system is
unavailable. In an emergency evasive
maneuver, the ESC system will not engage
to assist in maintaining stability. ESC “Full
Off” mode is intended for off-highway or
off-road use only.
The Electronic Stability Control (ESCyf
cannot prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. ESC cannot prevent all
accidents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also
cannot prevent collisions.

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.
