Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for recreational towing.
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and
rear drive shaft from the powertrain, and will allow the vehicle to roll, even if the
automatic transmission is in PARK (or manual transmission is in gear). The
parking brake should always be applied when the driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop.
2. Press and hold the brake pedal.
3. Shift the automatic transmission into NEUTRAL or depress the clutch pedal on a
manual transmission.
4. Turn the engine OFF.
5. Shift the transfer case lever into NEUTRAL (N).
6. Start the engine.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual transmissions) for five
seconds and ensure that there is no vehicle movement.
9. Repeat Steps 7 and 8 with automatic transmission in DRIVE or manual transmis-
sion in first gear.
10. Turn the engine OFF.
11. Firmly apply the parking brake.
12. Shift the transmission into PARK or place manual transmission in gear (NOT in
NEUTRAL).
CAUTION!
Damage to the transmission may occur if the transmission is shifted into PARK
with the transfer case in NEUTRAL (N) and the engine running. With the transfer
case in NEUTRAL (N) ensure that the engine is OFF before shifting the transmis-
sion into PARK.

INSTRUMENT CLUSTER WARNING LIGHTS
-ElectronicStabilityControl(ESC)Activation/MalfunctionIndicatorLight
If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the
engine running, a malfunction has been detected in the ESC system. 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), we recommend you drive to
the nearest service center and have the vehicle serviced immediately.
The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires
lose traction and the ESC system becomes active. If the light begins to flash during
acceleration, ease up on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing road conditions. The light
also flashes when TCS is active. To improve the vehicle's traction when starting off in
deep snow, sand or gravel, it may be desirable to switch the ESC system to Partial Off
mode by momentarily pressing the ESC Offswitch.
-TirePressureMonitoringSystem(TPMS)Light
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
WHAT TO DO IN EMERGENCIES
105

- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on it may indicate that the parking brake is
applied, that the brake fluid level is low, or that there is a problem with the anti-lock
brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS), are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

107

The light also will turn on when the parking brake is applied with the ignition switch
in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree
of brake application.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., may
illuminate the MIL after engine start. The vehicle should be serviced if the light stays
on through several typical driving cycles. In most situations, the vehicle will drive
normally and not require towing.
If the MIL flashes when the engine is running, serious conditions may exist that could
lead to immediate loss of power or severe catalytic converter damage. We recommend
you do not operate the vehicle. Have the vehicle serviced immediately.
-Electronic Stability Control (ESC ) OFF Activation/Malfunction Warning Light
If the ESC OFF warning light comes on continuously with the engine running, a
malfunction has been detected.
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), we recommend
you drive to the nearest service center and have the vehicle serviced immediately.
-ChargingSystemLight
This light shows the status of the electrical charging system. If the charging system
light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound when this
light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.

- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS).
If the light is not on during starting, stays on, or turns on while driving, we recommend
you contact the nearest authorized dealer and have the vehicle serviced immediately.
- Electronic Throttle Control (ETC) Indicator Light
This light informs you of a problem with the system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized dealer immediately. If the light is flashing when the engine
is running, immediate service is required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have the
vehicle serviced by an authorized service center immediately.
Oil Change Indicator
Message
If an “oil change” message (shown as “Change Oil Soon” and “Oil Change Needed”)
appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
1. Turn the ignition switch to the ON/RUN position (do not start engine).
2. Fully depress the accelerator pedal three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
- Low Fuel Warning Light
If the Low Fuel Warning Light comes on the fuel level is approximately 2.8 gal
(10.6 L) this light will turn on and a single chime will sound until fuel is added.
- Seat Belt Reminder Light
When the ignition switch is first turned to ON/RUN, this light will turn on for four to eight
seconds as a bulb check. During the bulb check, if the driver's seat belt is unbuckled,
a chime will sound. After the bulb check or when driving, if the driver seat belt remains
unbuckled, the Seat Belt Reminder Light will flash or remain on continuously.
WHAT TO DO IN EMERGENCIES
109

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do not
increase engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the
engine cooling system and turning the A/C off can help remove this heat.
•You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
