Driving while you tow
When towing a trailer:
•
Keep your speed no faster than 70 mph (112 km/h) during the first 500
miles (800 km) of towing a trailer, and don’t make full throttle starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in the
Driving chapter.)
•
Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in theInstrument Cluster chapter.
•Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.

3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to Fuses and relaysin theRoadside
Emergencies chapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the
LOCK position and remove the key whenever you leave your
vehicle.
WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

The fuel pump shut-off switch is
located under the right-hand side of
the glove box, just above the carpet.
To reset the switch:1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the switch by pushing in on the
reset button.
4. Turn the ignition ON.
5. Wait a few seconds and return the key to OFF.
6. Make another check for leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note: Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
