When trouble arises
SEQUOIA_OM_USA_OM0C013U_19MY
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergen cy
towing eyelets. This should only be attempted on hard surfaced roads
for at most 50 miles (80 km) at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes . The
vehicle’s wheels, drive train, a xles, steering and brakes must be in
good condition.
Securely attach cables or chains to the towing hooks.
Take care not to damage the vehicle body
Enter the vehicle being towed and start the engine.
If the engine does not start, turn the engine switch to the “ON” posi-
tion.
4WD models:
Turn the four-wheel drive control switch to the “2WD” position.
Shift the shift lever to N and release the parking brake.
When the shift lever cannot be shifted: P. 2 0 4
■While towing
If the engine is not running, the power assist for the brakes a nd steering will
not function, making steering and braking more difficult.
