2009 JEEP WRANGLER UNLIMITED warning

WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” ESP mode is intended for
off-road use only.
4L Range (4WD Models)
ESP Off
This is the normal operating mode for ESP in 4L range.
Whenever the vehicle is started in 4L range, or the
transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESP system will be in this
mode. In 4L range, 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 (48 km/h). At
40 mph (48 km/h), the normal ESP stability functionreturns but TCS remains off. When the vehicle speed
drops below 35 mph (40 km/h), the ESP system shuts off.
The ESP is off at low vehicle speeds in 4L range so that it
will not interfere with off-road driving, but the ESP
function returns to provide the stability feature at speeds
above 40 mph (48 km/h). The “ESP/TCS Indicator
Light” will always be illuminated in 4L range when ESP
is off.
NOTE:
The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
326 STARTING AND OPERATING

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

WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.

WARNING! (Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.1. Remove the spare tire, jack and tools from the stored
location.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Assemble the jack and jacking tools. Connect the jack
handle driver to the extension, then to the lug wrench.

WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent.
•Personal injury or property damage due to battery
explosion.
•Damage to the charging system of the booster
vehicle or of the immobilized vehicle.
•You should not try to start your vehicle by pushing

could cause the battery to explode.(Continued)

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Power Disc Brakes
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake Master Cylinder
The fluid level in the master cylinders should be checked
whenever the vehicle is serviced. If necessary, add fluid
to bring level to the full level mark on the side of the
reservoir of the brake master cylinder. With disc brakes,fluid level can be expected to fall as the brake pads wear.
If the brake fluid level is abnormally low, check system
for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
