With the ABS malfunctioning, the BAS and ESP will be
disabled. In this condition, both malfunction indicator
lights come on while the engine is running. If the
malfunction indicator light stays illuminated, have the
BAS and ESP checked at your authorized dealer as soon
as possible.
Electronic Stability Program (ESP)
The ESP enhances directional control and reduces wheel-
spin under various driving conditions. When ESP is
active, engine torque is limited and the ESP warning light
starts to flash.In winter operation, the effectiveness of the ESP can be
enhanced by equipping the vehicle with DaimlerChrysler
recommended mud and snow (M+S) rated radial-ply
tires and/or snow chains.
WARNING!
ESP cannot prevent the natural laws of physics from
acting on the vehicle, nor can it increase the traction
afforded. The ESP cannot prevent accidents, includ-
ing those resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user’s safety or the safety of others.
The ESP warning light starts to flash at any vehicle speed
as soon as the tires lose traction and the wheels begin to
spin.
146 STARTING AND OPERATING
Page 148 of 288

If the BAS/ESP malfunction indicator light is still illumi-
nated, the vehicle should be serviced at an authorized
dealer.
ESP Control switch
The ESP control switch is located in the center console.
When the ESP is switched off, the warning light in the
instrument cluster comes on. When the ESP is switched
on, the warning light goes out.
To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand, or gravel,
switch off the ESP by pressing the upper half of the ESPswitch. The ESP warning light will then be continuously
illuminated. With the ESP system switched off, the en-
gine torque reduction feature is cancelled. Therefore, the
enhanced vehicle stability offered by ESP is unavailable.
CAUTION!
Snow chains should never be used without the
recommended mud and snow (M+S) rated radial-ply
tires. Damage to your vehicle may result from such
usage.
ESP always operates under braking, even with the switch
in the OFF position.
If one drive wheel loses traction and begins to spin, the
ESP system will apply the brake at the affected wheel
until the wheel regains sufficient traction. The traction
control engages at approximately 24 mph (40 km/h), and
switches off at 50 mph (80 km/h).

To return to the enhanced vehicle stability offered by ESP,
press the lower half of the switch (the ESP warning light
goes out).
Anti-Lock Brake System (ABS)
The ABS gives increased vehicle stability and brake
performance under most braking conditions. The system
automatically “pumps” the brakes during severe braking
conditions to prevent wheel lock-up. The system operates
to prevent wheel lock-up and help avoid skidding on
slippery surfaces.
NOTE:The ABS improves steering control of the ve-
hicle during hard braking maneuvers.
The ABS prevents the wheels from locking up above a
vehicle speed of approximately 5 mph (8 km/h)
independent of road surface conditions.
At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal, indicat-
ing that the ABS is in the regulating mode.
Keep firm and steady pressure on the brake pedal
while experiencing the pulsation. Continuous, steadybrake pedal pressure results in optimal braking power
while maintaining the ability to steer the vehicle.
In the case of an emergency brake maneuver, keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the in-
creased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.WARNING!
Significant over- or under-inflation of tires, or mix-
ing sizes of front or rear tires or wheels on the
vehicle can reduce braking effectiveness. Maintain
proper tire pressure and always use the tires and
wheels specified in this manual for your vehicle.

When the ABS malfunction indicator light in the instru-
ment cluster comes on while the engine is running, it
indicates that the ABS has detected a malfunction and has
switched off. In this case, the brake system functions in
the usual manner, but without antilock assistance. With
the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lights come on
with the engine running. If the charging voltage falls
below 10 volts, the malfunction indicator light comes on
and the ABS is switched off. When the voltage is above
this value again, the malfunction indicator light should
go out and the ABS is operational. If the malfunction
indicator light stays illuminated, have the system
checked at your authorized dealer as soon as possible.WARNING!
ABS cannot prevent the natural laws of physics from
acting on the vehicle, nor can it increase braking or
steering efficiency beyond that afforded by the con-
dition of the vehicle brakes and tires or the traction
afforded. The ABS cannot prevent accidents, includ-
ing those resulting from excessive speed in turns,
following another vehicle too closely, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.

TIRES
Please take the time to read the tire warranty booklet in
your Owner’s Manual package. It contains valuable
information on tire maintenance.
Specific recommendations on guidelines for long-term
tire storage should be requested of the tire manufacturer.
Please refer to the tire warranty booklet for contact
information.
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
1. Safety
WARNING!
Improperly inflated tires are dangerous and can
cause accidents.
•Under inflation increases tire flexing and can
result in tire failure.
•Over inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
•Over inflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
•Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
STARTING AND OPERATING 153

Page 154 of 288
2. Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on the face of the driver’s door latch pillar.The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
154 STARTING AND OPERATING
Page 156 of 288

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 accident. Don’t 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 an accident. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 35 mph (55 km/h).
See the paragraph on Freeing A Stuck Vehicle in Section
6 of this manual.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 35 mph (55 km/h) when you are stuck. And
don’t let anyone near a spinning wheel, no matter
what the speed.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPM) monitors
the pressure in all tires. The TPM system uses
wireless technology to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the valve stem,
transmit tire pressure readings to a computer which
monitors for low pressure. If low pressure is measured,
the TPM Indicator Light will illuminate.
The TPM system informs you of a low tire pressure
condition. If this occurs, correct your tire inflation pres-
sure as soon as possible, and inspect all of your tires. Be
sure to use a high quality gauge when adjusting pressure.
The TPM system is designed to periodically monitor your
tire pressure but cannot be expected to function as a tire
pressure gauge. There can be a delay between the instant
you adjust the air pressure in a tire and when the system
updates the display. The TPM system is not intended to
provide you with notification of rapid air loss.
The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the tire label.
NOTE:A TPM system does not replace normal tire
maintenance.
CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do
not use aftermarket tire sealant or balance beads as
damage to the sensors may result. The standard
TIREFIT system (see Tirefit Tire Repair and Jacking
Instructions in the What To Do In Emergencies
section) is specifically designed to operate in con-
junction with the TPM system, and will not damage
the sensors.
