Retained Accessory Power (RAP)
These vehicle accessories may be used for up to
10 minutes after the engine is turned off.
•Audio System
•Power Windows, if equipped
•Sunroof, if equipped
The power windows and sunroof will continue to work
for up to 10 minutes or until any door is opened.
The radio will work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to OFF/LOCK, the radio will continue to work
for 10 minutes or until the driver’s door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the vehicle when it is already moving, use
N (Neutral) only.
Notice: Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.
Manual Transmission
The shift lever should be in N (Neutral) and the parking
brake engaged. Hold the clutch pedal down to the
floor and start the engine. The vehicle will not start if the
clutch pedal is not all the way down.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to ACC/ACCESSORY or LOCK/OFF.
3-22
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds, especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Push the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool. When the engine starts, let
go of the key and accelerator. If the vehicle
starts briefly but then stops again, repeat the
procedure. This clears the extra gasoline from the
engine. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently until the oil warms up and
lubricates all moving parts. Notice:
The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather condition at or below 0°F ( −18°C). Vehicles
with am engine coolant heater should be plugged in at
least four hours before starting. An internal thermostat
in the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
3-23
If parking the rig on a hill:1. Press the brake pedal, but do not shift into P (Park) yet for an automatic transmission, or into gear for a
manual transmission. Turn the wheels into the
curb if facing downhill or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply the parking brake, and then shift into P (Park) for an automatic
transmission or R (Reverse) for a manual
transmission.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply the regular brakes and hold the pedal down while you:
•Start the engine.
•Shift into a gear.
•Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See Scheduled Maintenance on page 7-3
for more on this. Things that are especially important in
trailer operation are automatic transmission fluid (do
not overfill), engine oil, drive belt, cooling system
and brake system.
Each of these is covered in this manual, and the Index
will help to find them quickly. When trailering, it is a good
idea to review this information before starting the trip.
Check periodically to see that all hitch nuts and bolts are
tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating on
page 6-27.
Towing a Trailer (Manual
Transmission)
Do not tow a trailer if the vehicle is equipped with a
manual transmission.
