Crash and Breakdown Information
We recommend the use of a wheel lift and
dollies or flatbed equipment to tow your
vehicle. Vehicle damage could occur if
towed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehicles
must have their designated drive wheels
off the ground regardless of towing
direction. Use tow dollies to prevent
damage to the transmission.
All-wheel or four-wheel drive vehicles
require that all wheels be off the ground
using a wheel lift and dollies or flatbed
equipment. This prevents damage to the
transmission and drive system.
Note: You need to switch on the ignition to
unlock the steering.
Note: Make sure you check the steering
column before towing. It could lock if the
battery is dead.

FAIL-SAFE COOLING

WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs due to
overheating.
The fail-safe distance depends on outside
temperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLING
WORK
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
Engine power is limited.
The air conditioning system turns off.

Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine.
Note: Have your vehicle checked as soon
as possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODE
IS ACTIVATED
WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
