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 effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h (45 mph) to reduce the possi-
bility of engine and transmission
overheating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transmission/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 minimize
heat build-up and extend the life of
your transmission.
NOTICE
To prevent engine and/or trans-
mission 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
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 max-
imum gross vehicle weight and
maximum trailer weight, it can
cause the engine or transmis-
sion 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.

• You must decide your vehicle
speed according to trailer weight
and uphill grade.
• Vehicles equipped with a dual
clutch transmission when tow-
ing a trailer on steep grades, the
clutch in the transmission could
overheat.
When the clutch is overheated,
gauge
the safe protection
engages. If the safe protection
mode engages, the gear posi-
tion indicator on the cluster
blinks with a chime sound.
At this time, a warning message
will appear on the LCD display
and driving may not be smooth.
If you ignore this warning, the
driving condition may become
worse.
To return to normal driving con-
dition, stop the vehicle on a flat
road and apply the foot brake for
a few minutes before driving off.
