INSTRUMENT CLUSTER
DISPLAY — IF EQUIPPED
Your vehicle may be equipped with an instru-
ment cluster display, which offers useful in-
formation to the driver. With the ignition in
the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and
display the total miles, or kilometers, in the
odometer. Your instrument cluster display is
designed to display important information
about your vehicle’s systems and features.
Using a driver interactive display located on
the instrument panel, your instrument clus-
ter display can show you how systems are
working and give you warnings when they
aren’t. The steering wheel mounted controls
allow you to scroll through and enter the main
menus and submenus. You can access the
specific information you want and make se-
lections and adjustments.

The light will illuminate when the ignition is
in the ON/RUN position before engine start.
If the bulb does not come on when turning
the ignition switch from OFF to ON/RUN,
have the condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
WARNING!
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in
sequence.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact your au-
thorized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)

As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale willflash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
CAUTION!
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
function checked.

• Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s respon-
sibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the “Tire
Pressure Monitoring Telltale Light.”
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Base System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.NOTE:
It is particularly important for you to check
the tire pressure in all of your tires regularly
and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS)
consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in
the spare wheel if the vehicle is equipped
with a matching full size spare wheel and tire
assembly. The matching full size spare tire
can be used in place of any of the four road
tires. A low spare tire will not cause the “Tire
Pressure Monitoring Telltale Light” to illumi-
nate or the chime to sound while stowed in
the spare location.
The “Tire Pressure Monitoring Tell-
tale Light” will illuminate in the in-
strument cluster, a “LOW TIRE
PRESSURE” message will display in the in-
strument cluster, and an audible chime will
be activated when one or more of the four
active road tire pressures are low. Should thisoccur, you should stop as soon as possible,
check the inflation pressure of each tire on
your vehicle, and inflate each tire to the
vehicle's recommended cold placard pres-
sure value. The system will automatically
update and the “Tire Pressure Monitoring
Telltale Light” will extinguish once the up-
dated tire pressures have been received. The
vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) to
receive this information
The “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds, and will
remain on solid when a system fault is de-
tected. The system fault will also sound a
chime. If the ignition key is cycled, this
sequence will repeat, providing the system
fault still exists. The “Tire Pressure Monitor-
ing Telltale Light” will turn off when the fault
condition no longer exists. A system fault can
occur by any of the following scenarios:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same
Radio Frequencies as the TPM sensors.

WARNING!
• ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
WARNING!
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in thetread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.

After Starting
The idle speed is controlled automatically,
and it will decrease as the engine warms up.
Normal Starting — Diesel Engine
1. The gear selector must be in the NEU-
TRAL or PARK position before you can
start the engine.
2. Turn the ignition key to the ON position.
3. Watch for the “Wait To Start Light” in the
instrument cluster. Refer to “Instrument
Cluster” in “Getting To Know Your Instru-
ment Panel” for further review. It will glow
for two to ten seconds or more, depending
on engine temperature. When the “Wait
To Start Light” goes out, the engine is
ready to start.
4. Tip Start Feature (Automatic Transmission
Only)
Do notpress the accelerator. Turn the
ignition key to the START position and
then release it. The starter motor will
continue to run, and it will automatically
disengage when the engine is running. If
the engine fails to start, the starter willdisengage automatically in 25 seconds.
If this occurs, turn the ignition switch to
the LOCK position, wait 25 to 30 sec-
onds, then repeat the “Normal Starting”
procedure.
NOTE:
The starter motor may run up to 30 sec-
onds in very cold conditions until the
engine is started. The starter can be dis-
engaged by turning the ignition key to
the OFF position, if required.
5. Without Tip Start Feature (Manual Trans-
mission Only)
Turn the ignition switch to the START
position and release when the engine
starts. If the engine fails to start within
10 seconds, turn the ignition switch to
the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting”
procedure.
6. After the engine starts, allow it to idle for
approximately 30 seconds before driving.
This allows oil to circulate and lubricate
the turbocharger.
Diesel Engine Warm-Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 rpm during the
warm-up period, especially in cold, ambient
temperature conditions.
If temperatures are below 32°F (0°C), oper-
ate the engine at moderate speeds for five
minutes before full loads are applied.
Diesel Engine Idling — In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of
idling may be harmful to your engine because
combustion chamber temperatures can drop
so low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings and injector
