2007 JEEP WRANGLER Engine

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” mode is intended for off-
highway or off-road use only.
ESP/BAS Warning Lamp
The malfunction indicator lamp for the ESP is
combined with the BAS indicator. The yellow
“ESP/BAS Warning Lamp” in the instrument
cluster comes on when the ignition switch is
turned to the “ON” position. It should go out with the
engine running.If the “ESP/BAS Warning Lamp” comes on continuously
with the engine running, a malfunction has been detected
in either the ESP or the BAS system, or both. If this light
remains on after several ignition cycles, and the vehicle
has been driven several miles at speeds greater than 30
mph (48 km/h), see your authorized dealer as soon as
possible to have the problem diagnosed and corrected.
NOTE:
•TheESP/BAS Warning Lampcomes on momen-
tarily each time the ignition switch is turned ON.
•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.

Electrical Outlet Use With Engine Off
WARNING!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade the battery
even more quickly. Only use these intermittently and
with greater caution.
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the alternator to
recharge the vehicle’s battery.
•Power outlets are designed for accessory plugs only.
Do not hang any type of accessory or accessory
bracket from the plug.
CUP HOLDERS
In the center console there are two cup holders for the
front seat passengers.
NOTE:The cup holder insert is removable from the
console, for cleaning.

OFF, the wiper will automatically return to the “Park”
position. When the vehicle is restarted, the wiper will
resume function at whichever position the switch is set
at.If the swing gate flip-up window is open or the swing
gate is open, connection to the rear window wiper is
interrupted preventing activation of the rear wiper blade.
When the swing gate flip-up window or the swing gate is
closed, the rear wiper switch or the ignition switch needs
to be turned OFF, and then to ON to restart the rear
wiper.
NOTE: The rear swing gate will lock while the rear
wiper is operating. The gate will stay locked until the
wiper is turned off and the gate is unlocked (by key,
lock switch, or key fob).

fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.
2. Charging System Warning Light
This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging systemor the battery is low. Also, a chime will sound if the light
comes back on. See your authorized dealer immediately.
3. Front Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
4. Low Fuel Warning Light
When the fuel level reaches approximately 2 U.S.
Gallons (7.6L) this light will come on and remain on
until fuel is added. The “Low Fuel Warning Light”
may turn on and off again, especially during and after
hard braking, accelerations, or turns. This occurs due to
the shifting of the fuel in the tank.

turning the key from OFF to ON, have the condition
checked promptly.Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the “Malfunction Indicator
Light” may flash to alert serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
