Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:• Start your engine;
• Shift into gear; and
• Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
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.

Follow Normal Maintenance Schedule if the vehicle is usually operated where none of
the following conditions apply. If any of the following conditions apply, you must follow
the Maintenance Under Severe Usage Conditions.
• Repeated driving short distance of less than 5 miles (8 km) in normal temperature or
less than 10 miles (16 km) in freezing temperature
• Extensive engine idling or low speed driving for long distances
• Driving on rough, dusty, muddy, unpaved, graveled or salt-spread roads
• Driving in areas using salt or other corrosive materials or in very cold weather
• Driving in heavy dust conditions
• Driving in heavy traffic area
• Driving on uphill, downhill, or mountain road repeatedly
• Towing a trailer or using a camper, or driving with loads on the roof
• Driving as a patrol car, taxi, other commercial use of vehicle towing
• Frequently driving under high speed or rapid acceleration/deceleration
• Frequently driving in stop-and-go condition
• Engine oil usage which is not recommended (Mineral type, Semi-synthetic, Lower
grade spec, etc.)
If your vehicle is operated under the above conditions, you should inspect, replace
or refill more frequently than the following Normal Maintenance Schedule. After the
periods or distance shown in the chart, continue to follow the prescribed maintenance
intervals.
Information
• As it is normal for engine oil to be consumed during driving, the engine oil level should
be checked on regular basis.
• The engine oil change interval for normal operating conditions is based on the use of
the recommended engine specification. If the recommended engine oil specification
is not used, then replace the engine oil according to the maintenance schedule under
severe operating conditions.
