R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow, ice,
or sand without damaging the transmission, seeIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5-20.
N (Neutral):In this position, the engine does not connect
with the wheels. To restart when you are already moving,
use N (Neutral) only. Also, use N (Neutral) when the
vehicle is being towed. Use N (Neutral) if the vehicle
must be moved with the engine off for short distances.
Please seeTowing Your Vehicle on page 5-26.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving.
It provides the best fuel economy for the vehicle.
If you need more power for passing and you are:
Going less than about 35 mph (56 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (56km/h) or more, push the
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-12.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Maximum engine speed is limited to protect driveline
components from improper operation.

Section 3 Instrument Panel

Instrument Panel Cluster
The instrument panel cluster and Driver Information Center (DIC) are designed to show how the vehicle is running.
It shows how fast the vehicle is going, about how much fuel is left and many other things needed to drive safely and
economically. The instrument panel cluster indicator warning lights, gages and DIC messages are explained on
the following pages.
United States Base Cluster shown, Canada and Uplevel similar
3-42

Speedometer and Odometer
The speedometer displays the speed in either miles per
hour (mph) or kilometers per hour (km/h).
There is only one scale for mph and km/h. Use the Driver
Information Center (DIC) controls to switch between mph
and km/h. SeeDIC Operation and Displays on page 3-57
for more information. The cluster will calculate the proper
speed and move the needle to the correct position. Either
the MPH or the km/h telltale will illuminate, depending on
which measurement is chosen.
The odometer is part of the Driver Information
Center (DIC). SeeDIC Operation and Displays on
page 3-57for more information.
Trip Odometer
The trip odometer is part of the Driver Information
Center (DIC). SeeDIC Operation and Displays on
page 3-57for more information.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6700 rpm.
If the vehicle is continually driven at the fuel shut off
rpm, the engine could be damaged. Be sure to operate
the vehicle below the fuel shut off rpm or reduce the
rpm quickly when the fuel shuts off.
3-43

Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briey when the engine
is started. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the system is working
normally the indicator light
then goes off.
This light also comes on when one or more of the tires
is signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC) can accompany the light. SeeDIC
Warnings and Messages on page 3-60for more
information.
Stop and check the tires as soon as it is safe to do so.
If underinated, inate the tire to the proper pressure.
SeeTires on page 6-46for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light ashes for approximately 60 seconds
and then stays on for the remainder of the ignition
cycle. SeeTire Pressure Monitor System on page 6-55
for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This comes on briey
while starting the engine.
If it does not come on,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
3-50

Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of the vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect the vehicle’s
emission controls and can cause this light to come
on. Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
The following can prevent more serious damage to
the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
3-51

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 6-8. The diagnostic system can
determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
If the vehicle has been driven through a deep
puddle of water, the vehicle’s electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run
as efficiently as designed and may cause:
stalling after start-up, stalling when the vehicle
is changed into gear, misring, hesitation on
acceleration, or stumbling on acceleration.
These conditions might go away once the engine is
warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one
full tank of the proper fuel to turn the light off.
SeeGasoline Octane on page 6-5.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.
