Winter driving tips

Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
 Use fluids that are appropriate to
the prevailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
 Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.
*
: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.

Before installing tire chains, make sure to
disable all functions of the vehicle height
control of the electronically modulated
air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. (P.293)

used, or 30 mph (50 km/h), which-
ever is lower.
