overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
WARNING!
In the “Partial Off” mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.All 4WD vehicles in Auto and 4HI Modes can also
choose the following ESP operating mode. This is
the only ESP operating mode in 4LO:Full Off
This mode is intended for off-road use when ESP stability
features could inhibit vehicle maneuverability due to trail
conditions. This mode is entered by depressing and
holding the ESP OFF switch for five seconds when thevehicle is stopped and the engine is running. After five
seconds, the “ESP/TCS Indicator Light” will illuminate
and the “ESP OFF” message will appear in the odometer.
Press and release the trip odometer button located on the
instrument cluster to clear this message.
NOTE:
The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
In this mode, ESP and TCS, except for the “Limited Slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h), the system returns to “Partial Off”
mode, described above. When the vehicle speed drops
below 35 mph (56 km/h), the ESP system shuts off. ESP
is off at low vehicle speeds so that it will not interfere
with off-road driving but ESP function returns to provide

the stability feature at speeds above 40 mph (64 km/h).
The “ESP/TCS Indicator Light” will always be illumi-
nated when ESP is off. To turn ESP on again, momen-
tarily depress the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.
“ESP Off” is the only operating mode for ESP in 4WD
LOW. Whenever the vehicle is started in 4WD LOW or
the transfer case (if equipped) is shifted from 4WD LOCK
or Neutral, to 4WD LOW, the ESP system will be in this
mode.
WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. “ESP Off”
mode is intended for off-highway or off-road use,
only.
ESP/BAS Warning Light and ESP/TCS Indicator
LightThe malfunction indicator for the ESP is combined with
the BAS indicator. The “ESP/BAS Warning Light” and
the “ESP/TCS Indicator Light” in the instrument cluster
both come on when the ignition switch is turned to the
ON position. They should both go out with the engine
running. If the “ESP/BAS Warning Light” comes on
continuously with the engine running, a malfunction has
been detected in either the ESP or BAS system, or both. If
this light remains on after several ignition cycles, and the
vehicle has been driven several miles/kilometers at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
NOTE:•
The “ESP Indicator Light” and the “ESP/BAS Warning
Light” come on momentarily each time the ignition
switch is turned ON.
344 STARTING AND OPERATING

•
Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•
The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal. The sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
TSC (Trailer Sway Control)The TSC system uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the appro-
priate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the
appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in Section 5 of this manual for moreinformation on towing a trailer with your vehicle. When
TSC is functioning, the “ESP/TCS Indicator Light” will
flash, the engine power may be reduced and you may
feel the brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is disabled
when the ESP system is in the Partial Off or Full Off
modes.
TSC is only active in the default “ESP On” mode. TSC can
be disabled by pressing the ESP OFF switch and entering
“ESP Partial Off” mode. It is not active in the “ESP Partial
Off” or “ESP Off” modes. Please refer to the ESP portion
of this section for an explanation of the different ESP
operating modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.

TIRE SAFETY INFORMATION
Tire Markings
NOTE:•
P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•
European-Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letterPis absent from this tire
size designation. Example: 215/65R15 96H.
•
LT (Light Truck) - Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•
Temporary spare tires are high-pressure compact
spares designed for temporary emergency use only.

dards Code (TIN) 4 — Maximum Load

Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•
High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

EXAMPLE:
Service Description: 95= Load Index
— A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
— A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
— The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification: \b....blank....\b = Absence of any text on the sidewall of the tire indicates a Standard Load (SL) tire
Extra Load (XL) = Extra load (or reinforced) tire
Light Load = Light load tire
C, D, E = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load — Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure — Maximum pressure indicates the maximum permissible cold tire inflation pressure for this
tire
348 STARTING AND OPERATING

Tire Identification Number (TIN)The TIN may be found on one or both sides of the tire,
however, the date code may only be on one side. Tires
with white sidewalls will have the full TIN, including the
date code, located on the white sidewall side of the tire.Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle. If the TIN is not found on
the outboard side, then you will find it on the inboard
side of the tire.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
— This symbol certifies that the tire is in compliance with the U.S. Department of Transportation tire
safety standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)
ABCD = Code used by the tire manufacturer (one to four digits)
03 = Number representing the week in which the tire was manufactured (two digits)
—03 means the 3rd week.
01 = Number representing the year in which the tire was manufactured (two digits)
—01 means the year 2001
— Prior to July 2000, tire manufacturers were only required to have one number to represent the year
in which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991
