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.

SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turn-
ing the ignition OFF and ON again may reset the ABS if
the fault detected was only momentary.
WARNING!
•When the ABS intervenes and you feel the brake
pedal pulsating, do not reduce the pressure, but
hold it down firmly and confidently; in doing so
(Continued)
WARNING! (Continued)
you will brake in the shortest distance possible,
depending on the current road conditions.
• For maximum efficiency of the braking system, a
bedding-in period of about 311 miles (500 km) is
required: during this period it is advisable to
avoid sharp, repeated and prolonged braking.
• If the ABS intervenes, this indicates that the grip
of the tires on the road is nearing its limit: you
must slow down to a speed compatible with the
available grip.
• The ABS can’t overrule the natural laws of phys-
ics, and can’t increase the grip available according
to the condition of the road.
• The ABS cannot prevent accidents, including
those due to excessive speed on corners, driving
on low-grip surfaces or aquaplaning.
•
The capability of the ABS must never be tested
irresponsibly and dangerously, in such a way as to
compromise personal safety and the safety of others.
• For the correct operation of the ABS, the tires
must of necessity be the same make and type on
all wheels, in perfect condition and, above all, of
the prescribed type and dimensions.
88 SAFETY

When you are in a severe braking condition involving
the use of the ABS, you will experience some pedal drop
as the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
System Intervention
A slight pulsing of the brake pedal and noise indicates
the intervention of the ABS: this is completely normal
when the system intervenes.
ESC (Electronic Stability Control System)
The ESC system improves the directional control and
stability of the vehicle in various driving conditions.
The ESC system corrects the vehicle understeer and
oversteer, distributing the brake force on the appropri-
ate wheels. The torque supplied by the engine can also
be reduced in order to maintain control of the vehicle.
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. ESC cannot pre-
vent all collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot pre-
vent collisions resulting from loss of vehicle
control due to inappropriate driver input for the
conditions. Only a safe, attentive, and skillful
driver can prevent collisions. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly

Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing the
distribution of brake pressure on the four wheels: the
system prevents the wheels on the inside of the corner
(less affected by the weight of the vehicle) from locking,
ensuring better stability and direction for the vehicle.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and inter-
venes in the event of sudden downshifting, or during
braking when the ABS intervenes, restoring torque to
the engine and thus preventing excessive drag at the
drive wheels, which may lead the wheels to lock and a
loss of vehicle stability, above all in low-grip conditions.
AntiSlip Regulation System (ASR)
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded

• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.

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

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

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.

Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
At least once a month:
•Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are
under-inflated.
• Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will pre-
vent moisture and dirt from entering the valve stem,
which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pres-
sure 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 sitting for a minimum of three hours. The cold tire inflation pressure must not exceed
the maximum inflation pressure molded into the tire
sidewall.
Check tire pressures more often if subject to a wide
range of outdoor temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa)
per 12°F (7°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage,
especially in the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or
conditions are such that the vehicle can be driven at
high speeds, maintaining correct tire inflation pressure
236 SERVICING AND MAINTENANCE

is very important. Increased tire pressure and reduced
vehicle loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or original
equipment vehicle dealer for recommended safe oper-
ating speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to
the maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•
The tire has not been driven on when flat.
• The damage is only on the tread section of your tire
(sidewall damage is not repairable).
•
The puncture is no greater tha na¼ofaninch (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size
and service description (Load Index and Speed Sym-
bol). Replace the tire pressure sensor as well as it is not
designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of
inflation pressure. This rapid loss of inflation is referred
to as the Run Flat mode. A Run Flat mode occurs when
the tire inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat mode it has
