Yellow Warning Lights
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is dis-
played 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 consumption may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corre-
sponding to each tire.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,

CAUTION! (Continued)
avoiding sharp braking and steering. If a tire punc-
ture occurs, repair immediately using the dedicated
tire repair kit and contact an authorized dealer as
soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
78 GETTING TO KNOW YOUR INSTRUMENT PANEL

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 indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue upon
subsequent vehicle 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 re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your authorized dealer to have your
sensor function checked.
— Anti-Lock Brake (ABS) Warning Light
This light monitors the Anti-Lock Brake System (ABS).
The light will turn on when the ignition is placed in the
ON/RUN or MAR/ON/RUN position and may stay
on for as long as four seconds.

Ready Alert Brake System (RAB)
This function activates automatically if the accelerator
pedal is released rapidly, reducing the brake pad travel
(both at front and back), with the aim of preparing the
braking system and enhancing its responsiveness, thus
reducing the stopping distance in the event of subse-
quent braking.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to “Tires” in
“Servicing And Maintenance” for information on howto properly inflate the vehicle’s tires. The tire pressure
will also increase as the vehicle is driven - this is normal
and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (TPMS Warning Light) illuminates,
you must increase the tire pressure to the recommended
cold placard pressure in order for the TPMS Warning
Light to turn off. The system will automatically update
and the TPMS Warning Light will turn off once the
system receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 30 psi (207 kPa). If the ambient temperature is
94 SAFETY

68°F (20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(158 kPa). This tire pressure is sufficiently low enough
to turn ON the TPMS Warning Light. Driving the
vehicle may cause the tire pressure to rise to approxi-
mately 27 psi (186 kPa), but the TPMS Warning Light
will still be ON. In this situation, the TPMS Warning
Light will turn OFF only after the tires are inflated to the
vehicle’s recommended cold placard pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire 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.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
5
SAFETY 95

correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster.
The 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 the tires on your vehicle regularly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning Light will illuminate in the instru-
ment cluster, an acoustic signal will be activated, and
the “Check left or right front/rear tire” text message
will display when one or more of the four active road
tire pressures are low. Should this occur, 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 pressure value.
The system will automatically update and the Tire
Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
96 SAFETY

Under any of the above circumstances, the following
checks need to be performed more frequently than
indicated in the Maintenance Plan:
•Check front and rear disc brake pad condition and
wear.
• Check cleanliness of tailgate locks.
• Check cleanliness and lubrication of chassis and
steering linkage.
• Visually inspect condition of: engine, gearbox, trans-
mission, pipes and hoses (exhaust - fuel system -
brakes) and rubber elements (gaiters - sleeves -
bushes - etc.).
• Check battery charge and battery fluid level (electro-
lyte).
• Visually inspect condition of the auxiliary drive belts.
• Check and, if necessary, change engine oil and re-
place oil filter.
• Check and, if necessary, replace air cleaner filter.
Using the vehicle on a track should be regarded as an
exception. The vehicle has been designed and manufac-
tured for road use. Change engine oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment.
This type of vehicle use is considered Severe Duty.
If the vehicle is operated in a dusty or dirty environ-
ment the engine air filter has to be changed every 6,500
miles (10,000 km).
Once A Month Or Before A Long Trip/Periodic
Checks
Every 600 miles (1,000 km) or before long trips, check
and, if necessary, top off the following:
•
Check engine oil level.
• Check brake fluid level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for un-
usual wear or damage.
• Check the fluid levels of the coolant reservoir and
brake master cylinder reservoir, and add as needed
• Check function of all interior and exterior lights.
Every 2,000 miles (3,000 km) check and, if necessary, top
up: engine oil level.
