Driving your vehicle
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
• When towing check automatic
transaxle 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.
