Driving Your Vehicle
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 dual clutch
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer minimises heat build up
and extend the life of your transmission.

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.
