Speedometer
Indicates the current vehicle
speed.
Engine coolant temperature
gauge
Indicates the temperature of the
engine coolant. At normal
operating temperature, the needle
remains within the normal area
(the area between the ªHº and
ªCº). If it enters the red section,
the engine is overheating. Stop the
vehicle, switch off the ignition and
let the engine cool. Refer to
Engine coolantin the
Maintenance and carechapter.
Never remove the coolant
recovery cap while the
engine is running or hot.
This gauge indicates the
temperature of the engine coolant,
not the coolant level. If the coolant
is not at its proper level or
mixture, the gauge indication will
not be accurate.

Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine may
overheat.
Always set the parking
brake fully and make sure
the gearshift is latched in P
(Park). Turn off the ignition
whenever you leave your vehicle.
Driving with a 4±speed
automatic transmission
Understanding gearshift
positions
Pull the gearshift lever towards
you and downward to move the
automatic gearshift.
Hold the brake pedal down
while you move the
gearshift lever from position to
position. If you do not hold the
brake pedal down, your vehicle
may move unexpectedly and
injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift is securely
latched in P (Park).

the outside. Do not grip the
spokes.
Drive cautiously to avoid vehicle
damage from concealed objects
such as rocks and stumps.
You should either know the terrain
or examine maps of the area
before driving. Map out your route
before driving in the area. For
more information on driving
off-road, read the ªFour Wheelingº
supplement in your owner's
portfolio.
If your vehicle gets stuck
If the vehicle is stuck, shift the
transmission in a steady motion
between forward and reverse
gears. Allow the transmission to
engage, then press lightly on the
accelerator.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine can
overheat.
Do not spin the wheels at
over 56 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
Sand
When driving over sand, try to
keep all four wheels on the most
solid area of the trail. Do not
reduce the tire pressures but shift
to a lower gear and drive steadily
through the terrain. Apply the
Driving

container to ensure the coolant
concentration in your vehicle is
such that the coolant will not
freeze at the temperature level in
which you drive during winter
months. Never increase the engine
coolant concentration above 60%.
Leave a 50/50 mixture of engine
coolant and water in your vehicle
year-round in non-extreme
climates.
What you should know about
fail-safe cooling
If the engine coolant supply is
depleted, this feature allows the
vehicle to be driven temporarily
before incremental component
damage is incurred. The ªfail safeº
distance depends on ambient
temperatures, vehicle load and
terrain.
How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The check engine light will
illuminate, indicating that vehicle
service is required.
The vehicle will still operate, but
will have limited engine power and
