Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get overheated and may
not operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have an automatic
transmission/dual clutch transmission,
you should drive in D (Drive) when
towing a trailer. Operating your vehicle
in D (Drive) when towing a trailer will
minimise heat build-up and extend the
life of your transmission.
NOTICE
To prevent engine and/or transmission
overheating:

V 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.

V You must decide your vehicle speed
according to the trailer weight and
uphill grade.
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 kerb (left if headed
down hill, right if headed up hill).
2. Shift the vehicle to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle).
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. Move the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or the 1st gear
when the vehicle is parked on a uphill
grade and in R (Reverse) on a downhill
(for Manual transmission vehicle).
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.

Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V 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,
automatic transmission/dual clutch
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 towbar.
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 towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V 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.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

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