CAUTION
■When the gross vehicle mass limit or maximum permissible axle capacity is
exceeded
Do not exceed the established speed limit for towing a trailer in built-up areas or
100 km/h (62 mph), whichever is the lower.
■Vehicle speed while towing
Observe the legal maximum speeds for trailer towing.
■Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while descend-
ing steep or long downhill grades.
■Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.
■To avoid accident or injury
●For vehicles with electronically modulated air suspension, set the vehicle height
to LO mode and turn off the electronically modulated air suspension to prevent
the vehicle height from automatically changing.
●Do not use cruise control when you are towing.
●Do not tow the vehicle with the compact spare tire installed.
