Driving Your Vehicle6-64
NOTICE
To prevent engine and/or transmission
overheating:

[ When towing a trailer on steep
grades (in excess of 6%) pay close
attention to the engine coolant
temperature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves towards “H” (HOT),
pull over and stop as soon as it is
safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

[ If you tow a trailer with the maximum
gross vehicle weight and maximum
trailer weight, it can cause the
engine or transmission to overheat.
When driving in such conditions,
allow the engine to idle until it cools
down. You may proceed once the
engine or transmission has cooled
sufficiently.

[ When towing a trailer, your vehicle
speed may be much slower than the
general flow of traffic, especially
when climbing an uphill grade. Use
the right hand lane when towing a
trailer on an uphill grade. Choose
your vehicle speed according to the
maximum posted speed limit for
vehicles with trailers, the steepness
of the grade, and your trailer weight.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2. Shift the gear to P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place wheel chocks under the trailer wheels on the down hill side of the
wheels.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking brakes.
7. Shift the gear to P (Park) when the vehicle is parked on a uphill grade and
in R (Reverse) on a downhill.
8. Shut off the vehicle and release the vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:

[Do not get out of the vehicle without
the parking brake firmly set. If you
have left the engine running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.

[ Do not apply the accelerator pedal to
hold the vehicle on an uphill.

Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your brakes and hold the brake pedal down
while you:

[ Start your engine;

[ Shift into gear; and

[ Release the parking brake.
2. Slowly remove your foot from 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 Towing a
Trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:

[Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.

[ Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)

[ When towing check transmission
fluid more frequently.

[ If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
