JEEP GRAND CHEROKEE 2007 WK / 3.G Owners Manual

To use the washer, pull the lever toward you and hold
while spray is desired. If the lever is pulled while in the
delay range, the wiper will operate for several seconds
after the lever is released, and then resume the intermit-
tent interval previously selected.
If the lever is pulled while in the OFF position, the wipers
will operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. You might not see other
vehicles or other obstacles. To avoid sudden icing of
the windshield during freezing weather, warm the
windshield with the defroster before and during
windshield washer use.
Mist
Use this feature when weather conditions make occa-
sional usage of the wipers necessary. Pull down and
release the control lever for a single wiping cycle.
Speed Sensitive Intermittent Wiper System
Use one of the five intermittent wiper speeds when
weather conditions make a single wiping cycle, with a
variable pause between cycles, desirable. Turn the end of
the lever to one of the five delay positions for the desired
delay interval. The delay can be regulated from a maxi-
mum of approximately 18 seconds between cycles, to a
cycle every 1/2 second.
NOTE:The wiper delay times depend on vehicle speed.
If the vehicle is moving less than 10 mph (16 km/h),
delay times will be doubled.

Rain Sensing Wipers—If Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multi-function lever to one of five settings
to activate this feature.
The sensitivity of the system can be adjusted with the
multi-function lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensi-
tive. Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 and 5 can be used if the

To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
feet (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 30 mph (48
km/h) for 3.7L/4.7L engines, 25 mph (40 km/h) for 5.7L
engines, and 14 mph (23 km/h) for 3.0L diesel engines,
the Speed Control will automatically disengage. If this
happens, you can push down on the accelerator pedal to
maintain the desired speed.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable
to lock out overdrive. Press the TOW/HAUL switch on
the lower center switch bank (below the Heating/Air
Conditioning controls).WARNING!
Leaving the Speed Control ON when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the
system OFF when you aren’t using it.
Driving Up or Down Hills
When going up or down hills, it is possible for your
vehicle to lose or gain speed, even though the Speed
Control is engaged. The automatic transmission may also
downshift to a lower gear, to maintain speed going up or
down hills. If going down a hill steep enough to cause the
vehicle to gain speed, press the brake pedal, which will
disengage the Speed Control and help slow your vehicle.

WARNING!
To help keep your vehicle under control, do not use
Speed Control under these conditions:
•When it is not possible to keep your vehicle at a set
speed.
•On slippery roads, such as on snow or ice.
•In heavy or varying traffic volume, in traffic that varies
in speed, or on winding roads.
•Be sure to turn the Speed Control switch to the OFF
position when not in use to avoid accidental engage-
ment.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation), and
ESP (Electronic Stability Program). All five systems work
together to enhance vehicle stability and control in vari-
ous driving conditions, and are commonly referred to as
ESP.
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 129

WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions. ABS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. 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.
TCS (Traction Control System)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the “Partial Off” or “Full Off” modes. Refer to “ESP
(Electronic Stability Program)” in this section.
