Passing other vehicles
■
Consider the total combined length of your vehicle and trailer and ensure that
the vehicle-to-vehicle distance is sufficient before executing lane changes.
Transmission information
■
To maintain engine braking efficiency, when using engine braking, when driv-
ing on a long steep downgrade, do not use the transmission in D. (P. 227)
If the engine overheats
■
Towing a loaded trailer up a long, steep incline in temperatures exceeding
30C (85F) may result in the engine overheating. If the engine coolant tem-
perature gauge indicates that the engine is overheating, turn the air condition-
ing off immediately, leave the road and stop the vehicle in a safe place.
(P. 535)
When parking the vehicle
■
Always place wheel chocks under the wheels of both the vehicle and trailer.
Firmly set the parking brake and shift the shift lever to P.
WARNING
Follow all the instructions described in this section. Failure to do so could cause an acci-
dent resulting in death or serious injury.
Trailer towing precautions

To avoid accident or injury
■
Do not tow a trailer when the compact spare tire is installed on your vehicle.
●
Do not tow a trailer when the tire installed is repaired with the emergency tire punc-
●
ture repair kit.

●

Vehicle speed in towing
