NOTE:Your vehicle's keyfob may have three, four or
five buttons (shown), depending on the optional features
purchased with your vehicle.
This system allows you to lock or unlock the doors and
liftgate or activate the panic alarm from distances a
minimum of 66 feet (20 meters) using a hand held radio
transmitter. The transmitter need not be pointed at the
vehicle to activate the system.
NOTE:The line of transmission must not be blocked
with metal objects.
To unlock the doors and liftgate:
Press and release the UNLOCK button on the key fob
once to unlock only the driver's door or twice to unlock
all the doors and liftgate. When the UNLOCK button is
pressed, the illuminated entry will initiate, and the
parking lights will flash on twice.The system can be programmed to unlock all the doors
upon the first UNLOCK button press by using the
following procedure:
²For vehicles equipped with the Electronic Vehicle
Information Center (EVIC), refer to ªRemote Key
Unlock,º under ªPersonal Settings (Customer Pro-
grammable Features),º under ªElectronic Vehicle In-
formation Center (EVIC)º in Section 3 of this manual
for details.
²For vehicles not equipped with the EVIC, perform the
following procedure:
1. Press and hold the LOCK button on a programmed
key fob.
2. Continue to hold the LOCK button at least 4 seconds,

To enter the vehicle while the engine is running during a
remote start, you must first unlock the vehicle using the
UNLOCK button on the key fob. After the vehicle is
unlocked, you have 60 seconds to enter the vehicle, insert
the key in the Ignition and move it to the RUN position,
otherwise the engine will cancel remote start and auto-
matically turn off.
Remote start will also cancel if any of the following occur:
²If the engine stalls or RPM exceeds 2500
²Any engine warning lamps come on
²The hood is opened
²The hazard switch is pressed
²The transmission is moved out of park
²Pressing the brake pedal.The vehicle can be started remotely up to a maximum of
two times. The vehicle is also allowed a maximum of one
failed start, where the remote start sequence was initiated
but the engine stopped cranking without starting. After
either of these conditions, or if the Vehicle Theft Alarm is
alarming, or if the PANIC button was pressed, the vehicle
must be reset by inserting a valid key into the ignition
and moving it to the RUN position, then back to LOCK.
DOOR LOCKS
Manual Door Locks
All the doors can be ªmanuallyº locked from the inside
by pushing down the door lock plunger, located at the
rear of the door. Both front doors may be opened from the
inside with the door lock plunger in the down or locked
position.
28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 (refer to the
table below for the speed for your specific engine), the
speed control will automatically disengage. If this hap-
pens, you can push down on the accelerator pedal to
maintain the desired speed.
Vehicles equipped with a Automatic transmission may
exhibit several downshifts under the above conditions.
To reduce the frequency of the downshifts and to im-
prove vehicle performance, it is advisable to lock out
overdrive by pressing the ªTOW/HAULº button located
at the end of the gear shifter.WARNING!
Speed Control can be dangerous where the system
can't maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don't use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.
REAR PARK ASSIST SYSTEM Ð IF EQUIPPED
NOTE:The manufacturer suggest disabling the Rear
Park Assist System when towing a trailer. Refer to
Overhead Console with Electronic Vehicle Information
(EVIC) ± If Equipped, Personal Settings (Customer Pro-
grammable Features) in section 3 of this Owner Manual.
This system is used to help drivers determine if an obstacle
is in the way of the vehicle while it is backing up in
addition to the use of inside rearview and outside mirrors.
152 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
²When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
354 STARTING AND OPERATING
Page 358 of 481

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the ªTOW
HAULº feature should be selected.
NOTE:Using the ªTOW HAULº feature while operat-
ing the vehicle under heavy operating conditions will
improve performance and extend transmission life by
reducing excessive shifting and heat build up. This action
will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See the Maintenance
Schedule in section 8 of this manual for transmission
fluid change intervals.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips Ð Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the ªTOW HAULº feature ON when driving in
hilly areas or shift the transmission to Drive position 2 on
more severe grades.
Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.

Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
þCity Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þrefer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
SNOWPLOW
NOTE:Do not use this vehicle for snowplow applica-
tions.
WARNING!
Snowplows, winches, and other aftermarket equip-
ment should not be added to the front end or your
vehicle. The airbag crash sensors may be affected by
the change in the front end structure. The airbags
could deploy unexpectedly or could fail to deploy
during a collision resulting in serious injury or
death.

CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in an acci-
dent. Do not expect that the airbag will perform as
described earlier in this manual
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational Towing 2WD Models
Recreational towing of 2WD models is not allowable.
Towing the vehicle with the transmission in Neutral can
cause severe transmission damage. Removal of the drive-
shaft for towing is not recommended since this allows
transmission fluid to leak out.
Recreational Towing 4WD Models
CAUTION!
Vehicles equipped with an NV 140 Transfer Case
(which has no neutral position) may NOT be used for
recreational towing.
