Driving on grades
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
hot and no longer operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h
(45 mph) to reduce the possibility of
engine and transaxle overheating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transaxle / dual clutch transmis-
sion, 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 transaxle.
CAUTION
• 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
across the dial towards "130/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.
• You must decide driving speed
depending on trailer weight
and uphill grade to reduce the
possibility of engine and
transaxle overheating.
