Fuel Gauge
Base Level
Uplevel
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on. When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.
Here are three things that some
owners ask about. None of these show
a problem with the fuel gauge:
.It takes a little more, or less fuel to
fill up than the gauge indicated. For
example, the gauge may have
indicated the tank was half full, but
it actually took a little more, or less
than half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner, speeding up or
braking.
.The gauge takes a few seconds to
stabilize after the ignition is turned
on and goes back to empty when
the ignition is turned off.

This gauge measures the temperature
of the vehicle's engine.
While driving under normal operating
conditions, if the red LED is
illuminated, the engine is too hot. Pull
off the road, stop the vehicle, and turn
off the engine as soon as possible.
Engine Coolant
Temperature Gauge
(Uplevel)
This gauge shows the engine coolant
temperature.
If the gauge pointer moves into the
red zone, the engine is too hot.
This reading indicates the same thing
as the warning light. It means that the
engine coolant has overheated. If the
vehicle has been operating under
normal driving conditions, pull off the
road, stop the vehicle, and turn off the
engine as soon as possible. See Engine
Overheating 0326 for more
information.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to
remind the driver to fasten their
seat belt.
Then the light stays on solid until the
belt is buckled. This cycle may
continue several times if the driver
remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.

If StabiliTrak/ESC is off, the Traction
Control System (TCS) is also off. To
turn ESC off and on, seeTraction
Control/Electronic Stability Control

If ESC and TCS are off, the systems do
not assist in controlling the vehicle.
Adjust driving accordingly.
Traction Control System
(TCS)/StabiliTrak Light
This light comes on briefly when the
vehicle is turned on.
If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally, the
indicator light turns off.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak/
ESC system are not fully operational
and may not assist in maintaining
control. Adjust driving accordingly. If the condition persists, see your
dealer as soon as possible. A Driver
Information Center (DIC) message
may display.
The light flashes when the TCS and/or
the StabiliTrak/ESC system is actively
working.
See
Traction Control/Electronic Stability
Control 0240.
Engine Coolant
Temperature Warning Light
On some vehicles this light comes on
briefly while starting the vehicle. If it
does not, have the vehicle serviced by
the dealer. If the system is working
normally the indicator light goes off.
For vehicles with the reconfigurable
cluster, this light may not come on
when starting the vehicle.
Caution
The engine coolant temperature
warning light indicates that the
vehicle has overheated. Driving with
this light on can damage the engine
and it may not be covered by the
vehicle warranty. See Engine
Overheating 0326.
The engine coolant temperature

DRIVING AND OPERATING 303
necessary to go much farther beyond
the passed vehicle before returning to
the lane. Pass on level roadways.
Avoid passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
that hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making TurnsCaution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects. Always
signal turns well in advance. Do not
steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is
not shifted down, the brakes may
overheat and result in reduced braking
efficiency.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating 0326.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
