hitch, total curb mass and drawbar load should not exceed the


The weight borne by the rear axle should not exceed the maximum
permissible rear axle capacity by 15% or more. Exceeding this
weight is dangerous.
The values for towing capacity were derived from testing conducted
at sea level. Take note that engine output and towing capacity will
be reduced at high altitudes.
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 lower.
Failing to observe this precaution may lead to an accident causing death or
serious injury.
