Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
• Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
• Allow more distance for stopping with a trailer attached.
• The trailer tongue weight should be no more than 10–15% of the
loaded trailer weight.
• After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
• Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
• Do not allow the static water level to rise above the bottom edge of
the rear bumper and
• Do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
• Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants anytime the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
